Laboratory frailty index

Laboratory frailty index raises the risk of mortality in humans (OR 1.26 per 0.1-unit increase, 95% CI 1.04–1.53).

“Sensitivity analysis using in-hospital mortality alone as the outcome confirmed the robustness of FIlab (OR 1.26 per 0.1-unit increase; 95% CI 1.04–1.53; P = 0.018).”

Laboratory frailty index predicts adverse outcomes in humans (OR 1.53 per 0.1-unit increase, 95% CI 1.34–1.75).

“In pooled multivariable analysis, FIlab remained independently associated with adverse outcomes (odds ratio [OR] 1.53 per 0.1-unit increase; 95% confidence interval [CI] 1.34–1.75; P < 0.001).”
