Forest plots for sensitivity of any degree of fibrosis (F0 vs. F1–4) along with their 95% confidence intervals (CIs). The plot includes four studies: Siddiqui 2019 [9], Chan 2017 [13], Kwok 2015 [15], and Liu 2021 [28]. Each study’s sensitivity is represented by a square, with the square size reflecting the study weight in the random effects model. Horizontal lines indicate the 95% CI for each study. The diamond at the bottom represents the pooled sensitivity estimate and its 95% CI, based on the random effects model. Heterogeneity among studies is quantified by I² (66%) and τ² (0.3995), with a p-value of 0.03 indicating significant heterogeneity.
