I Can See Health

After collecting the last data, Lu Chen returned to the dormitory.

The procedure of clinical scientific research is simple, collect data, process and analyze the data, draw conclusions, and finally write a paper.

At present, Lu Chen has only completed the first step.

But this first step is also the most important step, accounting for more than 50% of the overall workload.

"Ke Yue, thank you and your roommate for your help during this time." Lu Chen sent Ke Yue a WeChat message.

Ke Yue immediately replied: "If you have anything to do with the paper in the future, please tell me. I can help."

"OK."

However, Ke Yue's help is not needed for the next thing.

To process and analyze data, SPSS software is mainly used, and Lu Chen can do it alone.

…

In the next week, Lu Chen focused more on data processing.

On weekends, Lu Chen stayed in the dormitory as usual,

"Lu Chen, I heard that you have a very good person in the Department of Cardiology." Zhou Wei, who was moving bricks in the laboratory, sent him a WeChat message, "I published an article-by-article SCI as soon as I entered the lab!"

"Well, we still belong to District 8 in our hearts." Lu Chen replied, "What, do you want to get to know him? I can introduce him to you."

"Hey, forget it." Zhou Weidao said, "Let me tell you, my latest paper was also accepted! Although it is not a first-class paper, the score is pretty good, 3 points!"

"You're a good boy." Lu Chen praised.

A paper can have many authors.

But usually, only the corresponding author and the first author are acknowledged.

The corresponding author, usually a mentor, is the person who proposed the idea for the article.

The first author is the main experimenter or the person who wrote the paper.

The remaining second, third, and fourth authors all contributed to the paper, such as Ke Yue, who helped with data processing, etc.

Generally speaking, in any evaluation, priority, or promotion, only papers written by the corresponding author and the first author will be recognized.

However, if the score of an SCI paper is very high, such as Nature, Science, etc., and the impact factor score is above 100%, as long as you leave your name among the authors of the paper, no matter which author it is, then you can almost be in a third-rate paper. became a professor at the university.

"Oh, I did this experiment with my senior brother." Zhou Weidao, "So the tutor is communication, and the senior brother is first work, and gave me a second work. The idea for the next experiment is my own. If I can do it, it will definitely It’s just one thing!”

"Then I'll be waiting for your good news." Lu Chen said.

"You too, let's encourage each other." Zhou Weidao.

Everyone around me is working hard!

Lu Chen closed WeChat and continued processing the data at hand.

His data processing used multiple statistical methods with the support of clinical scientific research skill cards and statistical skill cards.

These include -Merier method, Log-rank method, multivariable COX regression analysis, etc.

Using a variety of statistical methods to repeatedly process experimental data, the final conclusion can be more convincing!

When Wang Zihao passed by Lu Chen, he accidentally caught a glimpse of his computer screen and was almost stunned.

The screen full of arithmetic symbols dazzled him.

"Lu Chen, how many statistical methods did you use?" Wang Zihao couldn't help but ask.

"Not many, just five kinds." Lu Chen said, "First use the chi-square test or Fisher's exact probability method to compare, then use the -Merier method to analyze, then use the Log-rank method to calculate whether there are statistical differences, and finally use the multivariate COX regression analysis confirms my conclusion."

Wang Zihao: "..."

Damn Versailles!

He only used a chi-square test, but Lu Chen actually used so many methods.

The gap is really quite big...

"Lu Chen, you did statistics by yourself? Didn't you ask for help from statistics majors?" Wang Zihao suddenly thought of this.

Statistics is a brand new major!

Where did Lu Chen get so much energy to learn statistics?

"Well, it's better to rely on ourselves. We can't rely on others to help us with statistics every time, right?" Lu Chen smiled.

"You are so awesome!" Wang Zihao gave Lu Chen a thumbs up.

He had to learn it, but he didn't think he had the patience or ability.

Seeing Lu Chen's concentration, Wang Zihao sighed a little.

Lu Chen's current results are inseparable from his hard work!

He has never seen Lu Chen go out to play during weekend breaks.

This can also explain why his sister Wang Ruoxi has a crush on Lu Chen.

However, Lu Chen, a straight man, didn't understand amorous feelings.

Wang Zihao felt a little pity and breathed a sigh of relief.

It's a pity because Lu Chen is a really nice person. After spending so long with him, he is definitely a reliable man.

He breathed a sigh of relief, because if they got married, wouldn't Lu Chen become his brother-in-law?

When we see each other every day, do we have to call him "brother-in-law"?

…

Lu Chen didn't know that Wang Zihao behind him was thinking about his own affairs.

He is still busy with data processing.

Now comes the final step of data processing!

That is to say, we need to see whether the conclusion drawn is statistically significant!

"This last step will reveal the outcome!"

Lu Chen felt a little nervous.

If there is no statistical significance, then his hard work over the past few months will be in vain!

Therefore, some experimenters often change the data in order to get a positive result if they do not get satisfactory results in this last step.

This is also an extremely common phenomenon in China.

Especially some hospitals in China.

Blindly pursuing papers ignores the fact that many doctors have no scientific research ability at all. So what should we do?

Only buying papers, falsifying data, or even plagiarism!

This is a very realistic and sad thing...

"Beep beep beep..."

The computer was running, and several unknown characters flashed in succession.

Finally, after waiting for five minutes, the computer screen output the final result.

P\u003c0.05——statistically significant!

In other words, in small-sample experimental studies, dapagliflozin can prevent heart failure in the early stages of acute myocardial infarction, and this proposition is established.

Lu Chen showed a look of joy and sighed: After five months, it's finally done! "

Others published several core journal papers in five months.

And he is still a zero egg!

…

After the data processing is completed, the only step left is to write the paper.

The writing of the paper is done step by step.

With data and conclusions, it's much simpler.

Lu Chen first completed the thesis writing in Chinese, and then translated the Chinese into English.

If you want to publish high-scoring SCI papers, Chinese journals do not have such influence for the time being, only foreign journals.

Even the most authoritative Chinese journal series in China has limited international influence.

This is also a very helpless reality!

The four top journals in the medical field are all located abroad.

They are NEJM (New England Journal of Medicine), The Lancet (Lancet Magazine), JAMA (American Medical Journal), and The BMJ (British Medical Journal). UU reading www. uukanshu.net

Lu Chen definitely doesn't dare to expect these four top journals now, but for his first paper, he will definitely find a more influential foreign journal.

However, Lu Chen didn't know much about the market conditions of foreign journals, so he asked Senior Sister Sun Guoguo.

Senior Sister Sun Guoguo has been involved in scientific research for many years and is very familiar with magazines in the cardiovascular field.

She immediately gave Lu Chen three suggestions.

"Clinics, Pediatrics."

Lu Chen searched for relevant journal information.

The impact factors are all between 1-2 points, and none exceed 3 points.

Lu Chen frowned, this was not in line with his expectations!
