Analysis of scientific research defects in periodical papers and solutions

Objective To analyze the shortcomings of statistical methods of journal articles and propose solutions. Methods Information All the literature of Basic and Medical Science and Technology database in CNKI database was used as sampling source, and the limited time was retrieved from November 10, 2014 to November 10, 2017. A total number of 1 456 417 articles were found, of which 100 were sampled each year by random number method. 300 articles were used to examine the application of statistical methods one by one, identifying the statistical defects and providing solutions. Results 126 out of the 300 papers analyzed used statistical methods, of which there were statistical defects. Most of the articles focused on statistics and P values without detailed annotation. The applicable conditions of statistical methods Mishandled and other issues, in view of these problems, this paper developed a statistical path map and question-answer computer system for clinical applications. Conclusions There are a lot of statistical flaws in the randomized papers. The statistical path map and the question-answering computer system proposed in this paper provide a solution to the clinical statistical problems.
