From: Prevalence and impact of acute renal impairment on COVID-19: a systematic review and meta-analysis
Meta-analysis of relative risk of CRRT application on severe and non-survival cases compared with non-severe and survival cases. a The forest plot represents the relative risk of CRRT application on severe patients compared with non-severe patients. b The forest plot represents the relative risk of CRRT application on non-survival cases compared with survival cases. Heterogeneity is defined based on the calculated I2 index, and fixed effect models are used to calculate the weights
