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.
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
Background: Nipple-sparing mastectomy (NSM) with immediate implant-based reconstruction is widely accepted and effective prophylactic surgical approach for women with high-risk of hereditary BC. However, anatomical factors-advanced breast ptosis and increased sternal notch-to-nipple (SN-N) distance-can increase technical difficulty and complication risk. Preshaping procedures may optimize anatomy and broaden NSM eligibility. This study evaluates the role of preshaping in facilitating safe NSM with implant-based reconstruction. Methods: We conducted a retrospective analysis of 84 patients who underwent prophylactic mastectomy at Vilnius University Hospital Santaros Klinikos between 2018 and 2024. All had confirmed pathogenic mutations associated with hereditary BC risk. At the time of analysis, 76 patients had completed mastectomy, while 8 had undergone only the preshaping procedure. Patients were divided into two cohorts: single-stage NSM with direct-to-implant reconstruction, and a two-stage approach involving initial preshaping surgery followed by delayed NSM. Anatomical features, surgical timing, complications were analyzed. Results: Among 76 patients, 63.2% underwent single-stage and 36.8% two-stage reconstruction. Two-stage patients had significantly greater SN-N distances (26.4 ± 3.1 cm vs. 21.6 ± 3.2 cm, Conclusions: Preshaping surgery effectively optimizes anatomy for NSM, reducing complications in patients with ptosis or extended SN-N distances. The two-stage approach offers safe and favorable outcomes in anatomically challenging cases.
