Fig. 4From: Machine learning algorithms’ accuracy in predicting kidney disease progression: a systematic review and meta-analysisCoupled forest plots for sensitivity and specificity. A All single-unit ML algorithms. B CKD subgroup. C IgAN subgroup. D Sensitivity analysis after eliminating outliers and data with small sample sizes. The gray square with a black point in the center showed study specific estimates of sensitivity and specificity. The width of solid black line showed their 95% confidence intervals. The diamond at the bottom of the figure was a combination of single-unit ML algorithm.The center of diamond represented the point estimates, and the width of diamond represented 95% confidence intervalsBack to article page
