This study aimed to evaluate and compare the validity and diagnostic accuracy of the FPI-6 and CA in determining adolescents’ flexible flatfoot between ages of 12 and 18 years, considering radiographic investigation as a reference standard measure.Design: Cross-sectional study.Setting: Governmental hospitals.Participants and Methods: A sample of 460 people (920 feet) with flexible flatfoot between the ages of 12 and 18 (15.23 ± 0.84 years) was enrolled in the study. The findings of the investigated measures were compared to the reference standard radiographic measure and plotted on the receiver operating characteristic (ROC) curve. The area under the ROC curve (AUC) was determined as a measure of FPI-6 and CA diagnostic accuracy. Intra-rater reliability, sensitivity, specificity, predictive values, and likelihood ratios of FPI-6 and CA were calculated and compared. The post-test probability of flatfoot was determined using the ...
