Outline
To analyze the design flaws and statistical issues present in medical papers submitted to core domestic journals, and to explore strategies for improving the quality of medical papers and submission acceptance rates.
A questionnaire survey was conducted to collect data on submissions to domestic core medical journals between January 2021 and December 2023. Quantitative empirical and qualitative analyses were performed.
A total of 306 clinical medicine research papers and 328 basic medicine research papers were included in the analysis. There was a statistically significant difference in the acceptance rates between these two categories (P<0.001), while no significant difference was found concerning the acceptance rates of papers supported by different levels of funding (P>0.05). Observational studies constituted 71.40% of all submissions; however, their acceptance rate was lower than that of experimental studies (43.75% vs. 53.66%, P<0.05). Various deficiencies were identified in the methodological design and statistical analysis reporting of the manuscripts. The main issues included unclear description of study design types, inadequate matching between groups, insufficient modeling and validation, neglect of sample size calculation, and errors in result reporting.
Significant flaws exist in the research design and statistical analysis reporting of medical manuscripts, with a considerable gap compared to internationally recognized medical reporting standards. Hospitals and medical schools should strengthen training in the latest medical research standards and statistical knowledge to improve the quality of academic papers and enhance research outcomes.
