Network diagram for the outcome of stillbirth in women with recurrent miscarriage. The nodes represent an intervention and their size is proportional to the number of trials comparing this intervention to any other. The lines connecting each pair of interventions represent a direct comparison and are drawn proportional to the number of trials making each direct comparison. Numbers on the lines represent the number of trials and participants for each comparison. The colour of the line is light green for moderate‐certainty evidence.
