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

backgroundMacromastia, particularly in its severe form-gigantomastia-is characterized by excessive mammary tissue growth and significantly impairs quality of life through physical symptoms, psychological distress and functional limitations. Reduction mammaplasty remains the standard of care, aiming to relieve symptoms while preserving breast function and aesthetics. Several surgical techniques based on vascular pedicles have been developed, including the superomedial and inferior pedicle approaches. However, few studies have compared these techniques in patients requiring large-volume resections.

methodsWe conducted a systematic review and meta-analysis comparing the inferior and superomedial pedicle techniques in patients with gigantomastia, defined as a resection volume ≥ 800 grams per breast. Multiple databases were searched for studies published from 2010 onward. Statistical analyses were performed using Review Manager 5.4.1, applying a random-effects model. Primary outcomes included postoperative complications, aesthetic results, and quality of life indicators. Ninety-five percent confidence intervals were calculated using the Mantel-Haenszel method. Heterogeneity was assessed using the I

resultsEight comparative studies were included. No statistically significant differences were found in the primary outcomes. However, trends favored the superomedial pedicle in most metrics, including overall complication rate, NAC necrosis and NAC sensitivity.

conclusionsBoth techniques appear to be safe and effective options for patients with severe macromastia. The superomedial pedicle may offer certain advantages in specific outcomes, but current comparative evidence remains limited. Further randomized controlled trials are needed to better inform surgical decision-making in this population.
