Patient Characteristics between Prepectoral and Dual-plane Groups among Comparative Studies10,13,16,24–26,28,30,31
| Variable | Prepectoral* | Dual-plane* |
|---|---|---|
| No. patients | 362 | 471 |
| No. breasts | 538 | 698 |
| Age (SD) | 50.99 (12.12) | 49.86 (11.13) |
| BMI (SD)† | 26.70 (4.58) | 25.86 (5.02) |
| Unilateral procedure | 57.26% | 58.06% |
| Smokers‡ | 4.74% | 11.71% |
| Diabetes‡ | 7.38% | 3.07% |
| Hypertension | 19.67% | 16.10% |
| Prior chemotherapy | 18.51% | 18.04% |
| Prior radiation | 6.63% | 5.88% |
| Postoperative chemotherapy | 24.12% | 23.64% |
| Postoperative radiation‡ | 13.33% | 21.04% |
| Prior breast surgery | 14.78% | 15.03% |
| Follow-up time, mo (range) | 7.00 (3–14) | 8.06 (3–14) |
*Weighted by sample size (number of patients) except for follow-up time, which is weighted by number of breasts.
†One study did not report BMI; however, the proportion of high BMI (>35) was significantly lower in the prepectoral group.
‡Significant difference determined by chi-square test (P < 0.05).
Walia et al13 did not report % unilateral. All procedures were assumed to be unilateral.
