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

backgroundTherapeutic mammoplasty (TM) is a well-established oncoplastic breast-conserving technique, particularly for patients with large ptotic breasts. However, evidence on the oncologic safety and cosmetic outcomes in East Asian patients who meet these anatomical criteria remains limited. This study evaluated the outcomes of TM combined with contralateral reduction mammoplasty in a cohort of East Asians.

methodsWe conducted a single-center retrospective observational study of consecutive patients who underwent TM with simultaneous contralateral reduction mammoplasty for breast cancer between April 2014 and March 2024. The primary endpoint was oncologic safety, assessed using the positive margin rate and local recurrence. The secondary endpoints included 1-year cosmetic outcomes, assessed using BCCT.core and the Harvard scale by blinded physicians.

resultsA total of 104 patients were included (mean age: 59.6 ± 10.6 years, mean body mass index: 28.4 ± 5.1 kg/m

conclusionsIn selected East Asian patients with relatively large ptotic breasts, TM combined with contralateral reduction mammoplasty demonstrated favorable oncologic safety and cosmetic outcomes.
