Fig 4 Forest plot for results from bayesian network meta-analysis (solid squares) and those from traditional pairwise meta-analysis (blank squares) for outcomes of all cause mortality, end stage renal disease, and doubling of serum creatinine levels. Squares represent pooled estimates of odds ratio. Lines for 95% confidence intervals represent 95% credible intervals in bayesian network meta-analysis and 95% confidence intervals in traditional pairwise meta-analysis. The result of a single trial is provided as direct evidence when traditional meta-analysis in a specific comparison is not feasible. Angiotensin receptor blocker (ARB) plus calcium channel blocker (CCB), ARB plus diuretic, and angiotensin converting enzyme (ACE) inhibitor plus ARB were not plotted owing to unstable estimated effects and extremely wide credible intervals
