Methodological quality of studies on prediction model published in Chinese nursing core journals in recent five years
Objective To appraise the methodological quality of studies on prediction model published in Chinese nursing core journals in the past five years,and to provide reference for the study of prediction models.Methods The articles on prediction model published in nursing core journals from January 1,2018 to December 31,2022 were retrieved.A Measurement Tool to Assess Risk of Bias and Applicability of Prediction Model(PROBAST)was used to evaluate the methodological quality of the prediction model.Results A total of 265 articles were included,and the overall risk of bias was high.The main problems included inappropriate research design,unreported and unused blind methods,insufficient sample size,and incorrect methods for screening predictors.Conclusion The methodological quality of the included predictive models needs to be improved,and the construction process needs to be standardized,thus to provide a more reliable basis for decision-making.
