Figure 1 - Treatment effect of intervention compared to control to prevent preterm birth in twin gestations compared to control group for spontaneous PTB<34 weeks and overall PTB<34 weeks
Figure 2 - Evidence network diagram of network meta-analysis comparisons for spontaneous PTB<34 weeks and overall PTB<34. The width of each edge is proportional to the number of randomized controlled trials comparing each pair of treatments, and the size of each treatment node is proportional to the number of randomized participants
