Obese Patients Undergoing Implant-based Breast Reconstruction: A Propensity Score-Matched Analysis.

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: Breast reconstruction following oncologic mastectomy is an integral component of comprehensive breast cancer care, with implant-based reconstruction consistently being reported to be the most commonly performed worldwide. Although immediate reconstruction offers the clear benefit of reducing the number of necessary surgical procedures and providing immediate aesthetic results, concerns persist regarding its feasibility in high-risk patient populations. Obesity has been suggested to be a potential contributor to lymphatic dysfunction and impaired lymphatic vasculature; both mechanisms can predispose patients to the development of postmastectomy lymphedema. Postmastectomy lymphedema is a chronic, debilitating condition with significant implications on quality of life, functional capacity, and healthcare utilization. Established risk factors include axillary lymph node dissection, radiation therapy, and the extent of mastectomy resection. Timing of reconstruction, however, especially in obese patients undergoing implant-based reconstruction, has not been clearly delineated. Methods: Retrospective TriNetX cohort of obese adults undergoing implant-based breast reconstruction compared immediate versus delayed timing using propensity matching, assessing short- and long-term complications, including lymphedema, via risk ratios and survival analyses. Results: Among 6082 obese patients, 1944 matched pairs underwent immediate or delayed implant-based reconstruction. Immediate reconstruction showed higher 90-day complications and a persistently increased risk of lymphedema through 5 years, confirmed by Kaplan-Meier and Cox regression analyses. Conclusions: Among obese patients undergoing implant-based breast reconstruction, immediate reconstruction is associated with higher rates of early postoperative complications and a persistent increase in postmastectomy lymphedema risk compared with delayed reconstruction.
