Fig. 1From: How robust are findings of pairwise and network meta-analysis in the presence of missing participant outcome data?A Heatmap of the proportion of total MOD in each intervention (percentages in white, main diagonal) and observed comparison (percentages in black, lower off-diagonal) in the network of antidepressants for participants with Parkinson’s disease [23]. B Heatmap of the robustness index (RI) values for every possible comparison in the network of antidepressants for participants with Parkinson’s disease [23]. The pairwise comparisons are read from left to right. Red cells indicate a lack of robustness (RI ≥ 0.28), and green cells indicate the robustness (RI < 0.28) of the primary analysis results for the corresponding comparisonBack to article page
