Comparison of Weighted Averages^* of Complication Rates between Prepectoral and Dual-plane Techniques.^{3,10,13,24–26,28,30,31}

Complication	Prepectoral (n = 8 studies, n = 338 patients, n = 499 breasts)	Dual-plane (n = 8 studies, n = 436 patients, n = 641 breasts)
Infection	3.75%	5.62%
Seroma	4.41%	4.08%
Hematoma	1.81%	2.14%
Flap necrosis	5.49%	5.80%
Explantation	4.90%	5.09%
Capsular contracture†	0.00%	14.79%
Dehiscence	2.93%	2.59%

*Pooled estimates weighted by sample size (number of breasts); significance not determined in pooled results.

†Significant difference determined by chi-square test (P < 0.05).
