1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundNipple-sparing mastectomy (NSM) offers improved aesthetics without compromising oncologic safety. Subpectoral breast reconstruction has long been standard practice, although prepectoral reconstruction has recently resurged in popularity. Due to this recent paradigm shift, studies comparing long-term outcomes by reconstructive plane are lacking.

methodsA retrospective review was conducted on consecutive NSMs with implant-based reconstruction in either the prepectoral or subpectoral plane from 2014 to 2018. Patient demographics, implant specifications, and operative details were collected to evaluate primary outcomes of prosthetic failure and unplanned reoperations by reconstructive plane. Secondary outcomes included animation deformity, capsular contracture, rippling, plane change, and minor revisions, including fat grafting. Bivariate and multivariate analyses were performed to assess outcomes.

resultsOverall, 405 NSMs were performed on 228 women (subpectoral = 202, prepectoral = 203), with a mean follow-up of 2.1 years (standard deviation 1.1). During the study period (2014-2018), a shift from subpectoral to predominantly prepectoral mastectomies occurred in 2017. Prepectoral reconstructions were more often direct-to-implant (DTI) compared with subpectoral (73.9% vs. 33.2%, p < 0.001). Prepectoral reconstruction demonstrated significantly reduced prosthetic failure (odds ratio [OR] 0.30, 95% confidence interval [CI] 0.14-0.65) and unplanned reoperations (OR 0.43, 95% CI 0.24-0.77) compared with subpectoral reconstruction after controlling for implant characteristics and other possible confounders. Prepectoral patients experienced decreased animation deformity overall (19.7% vs. 0.0%, p < 0.001), with plane changes seen in 10.6% of subpectoral reconstructions for animation deformity correction. Prepectoral patients experienced an increase in rippling (15.3% vs. 6.1%, p = 0.003) without a significant increase in fat grafting (subpectoral = 11.6% vs. prepectoral = 12.3%, p = 0.829).

conclusionsThis single-institution experience compares late complications of prepectoral and subpectoral implant-based reconstruction following NSM. Prepectoral reconstruction can be safely performed with improved understanding of mastectomy planes, readily affords DTI reconstruction, and reduces animation deformity at the expense of rippling.
