Fig. 2From: Potassium levels and the risk of all-cause and cardiovascular mortality among patients with cardiovascular diseases: a meta-analysis of cohort studiesForest plot for association between blood potassium levels and risk of mortality in patients with total and individual cardiovascular diseases expressed as comparison between hypokalemia, hyperkalemia and normokalemia; hyperkalemia and normokalemia together with hypokalemia. The diamond indicates the pooled RR estimates from random effects analysis, and horizontal lines indicate corresponding 95% CIs. CI, confidence interval; CVD, cardiovascular disease; HF, heart failure; MI, myocardial infarction; RR, relative riskBack to article page
