Table 1.

All-cause mortality: ORs (posterior mean with 95% intervals) for each pair-wise comparison of interventions, based on direct evidence alone (lower-left triangle) or direct and indirect evidence (upper-right triangle)

Lower-left results compare row-defining interventions against column-defining interventions. Upper-right results compare column-defining interventions against row-defining interventions.

In the meta-analysis of direct comparisons (reported in lower-left triangle), between-trial heterogeneity τ² was estimated as 0.009 (95% interval 0.001 to 0.08).

In the network meta-analysis (reported in upper-right triangle), between-trial heterogeneity τ² was estimated as 0.009 (95% interval 0.001 to 0.07).

The small superscript numbers in the cells of lower-left triangle indicate the numbers of randomised trials which compared the two interventions directly.

HD, high dose; LD, low dose.
