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
introductionChest masculinization surgery represents a key component of gender-affirming care for transgender men and has been associated with significant improvements in psychological well-being and reduction of gender dysphoria. Although established techniques such as double-incision mastectomy with nipple-areola complex grafting and periareolar approaches effectively remove breast tissue, postoperative chest contour may remain flat and lack pectoral definition in some patients. Autologous fat grafting has been widely used in cisgender male aesthetic surgery to enhance pectoral projection and muscular definition. However, its application during masculinizing mastectomy in transgender patients remains poorly described. This study evaluates the outcomes and safety of intramuscular pectoralis major fat grafting performed concurrently with chest masculinization surgery.
methodsA retrospective analysis of prospectively collected data was conducted on transgender patients who underwent chest masculinization surgery with simultaneous pectoralis major fat grafting between January 2022 and January 2025 at a single institution. Patients underwent either double-incision mastectomy with free nipple-areola complex grafting or ultrasonic-assisted subcutaneous mastectomy depending on breast characteristics. Autologous fat was harvested from the flanks, axillary pillar, or back and injected into the pectoralis major muscle in intramuscular and sub-muscular planes. Primary outcomes included patient satisfaction assessed at 12 months using the validated TRANS-Q questionnaire. Secondary outcomes included postoperative complications and revision procedures classified according to the Clavien-Dindo system.
resultsSixty transgender patients (120 mastectomies) were included. The mean age was 32.5 years, and the mean body mass index was 22.5 kg/m
conclusionsIntramuscular pectoralis major fat grafting combined with chest masculinization surgery appears to be a safe and effective strategy to enhance thoracic contour and improve masculine chest definition in transgender men. This integrated approach may optimize aesthetic outcomes and contribute to high levels of patient satisfaction and gender congruence.
