Lower-left results compare row-defining interventions against column-defining interventions. Upper-right results compare column-defining interventions against row-defining interventions.
The comparison of prostatectomy with observational management was not linked to the rest of the network, so this evidence was included in the meta-analysis of direct comparisons only.
In the meta-analysis of direct comparisons (reported in lower-left triangle), between-trial heterogeneity τ² was estimated as 0.04 (95% interval 0.003 to 0.29).
In the network meta-analysis (reported in upper-right triangle), between-trial heterogeneity τ² was estimated as 0.04 (95% interval 0.002 to 0.26).
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.
