HAVCR1 and renal fibrosis: Three studies (Ibrahim Fouad and Ahmed, 2021; Ahmedy et al., 2022; Ma et al., 2022) cited KIM-1 levels, demonstrating that compared to the model group, BBR significantly reduced KIM-1 in renal fibrosis animals (Sample size: 52; SMD = −9.88 (95% CI: −19.00 to −0.77), P < 0.001; χ2 = 35.30, I2 = 94.3%).
