Forest plots of patency rate under DA-LIVE and SA-LIVE.
(a random-effects model was used).

Forest plots of different patency criteria to compare the patency rate (random-effects model was used).
Fig 5.
Forest plots of different patency criteria to compare the patency rate of DA-LIVE and SA-LIVE.
(A) represents the forest plots where patency was defined as the presence of any sperm in the semen. (B) and (C) represent the forest plots where patency was defined as sperm concentration >10 thousand/ml and >1 million/ml (a random-effects model was used).

Forest plots of semen parameters under DA-LIVE and SA-LIVE.
(A) and (B) represent the forest plots of sperm motility and sperm concentration (random-effects model for eight and twelve studies, respectively).
