Forest plots of the sensitivity (A) and specificity (B) of ML models based on clinical, hormonal (laboratory) and imaging data for the diagnosis of CPP. Note-The dots correspond to the individual studies included in this analysis, and both sides of the line represent the 95% confidence interval. The narrower the line is, the greater the accuracy of the study and the greater the weight. The diamond corresponds to the pooled result. The intermediate vertical line represents an invalid line. Q statistic test card square value (chi-square), degree of freedom (df), p-values and I² statistic test results (Inconsistency (I- square)) correspond to heterogeneity test results. The Q test was used to assess heterogeneity, while the I² test was used to measure the size of heterogeneity. Heterogeneity was considered when p was less than 0.01. If I²<25%, no heterogeneity was noted. If the value of I² was between 25% and 50%, the degree of heterogeneity was considered to be small. If the value of I² was between 50% and 75%, heterogeneity was noted. If I²>75%, large heterogeneity was noted.
