Current status of medical researchers'understanding of P value
[Objective]To explore the understanding degree of medical students,researchers,and medical statistics teachers on P value in statistics and its related factors,so as to provide references for the improvement of medical statistics teaching.[Methods]Convenience sampling method was used to distribute 175 questionnaires through the online platform questionnaire star(Wenjuanxing).Based on case study,the questionnaire was designed with 6 true-or-false questions about P values.Accuracy rate of understanding on P value by medical students,researchers and professional teachers was evaluated through questionnaire survey.Descriptive analysis and multivariate logistic regression analysis were used to explore the related factors affecting the understanding of P value.[Results]A total of 170 questionnaires were collected,with 50 from the medical students,98 from the researchers,and 22 from the professional teachers,respectively.The results indicated that the professional teachers had the highest accuracy rate(89.5%),whereas the medical students had a relatively low accuracy rate(31.6%).Multivariate logistic regression analysis revealed that individuals with a doctoral degree,compared to those with a bachelor's degree or below,had a higher accuracy rate(OR=2.10,95%CI:1.18‒3.76,P=0.012).Additionally,researchers who had received training in medical statistics(OR=4.20,95%CI:2.23‒7.93,P<0.001)or medical research design courses(OR=2.40,95%CI:1.33‒4.33,P=0.004)exhibited higher accuracy rates.[Conclusion]Medical students and researchers generally have misunderstandings about P values.It is recommended to improve the understanding about P values,such as strengthening medical statistics teaching at the academic education levels,setting up medical research design courses,increasing student-led discussions,and intensifying continuing education and science popularization activities.
