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.

Abstract
backgroundRobot-assisted kidney transplantation (RAKT) is increasingly being adopted worldwide. Despite this growing interest, there remains a notable gap in the literature, especially concerning its effectiveness in immunologically high-risk patients compared to conventional open kidney transplantation (OKT). This study investigates the viability and success of RAKT in comparison with OKT, particularly for recipients with ABO incompatibility (ABOi).
methodsThis retrospective, single-center study included 239 living-donor transplants between October 2020 and February 2023, with 210 patients undergoing ABOi-OKT and 29 undergoing ABOi-RAKT. A composite of biopsy-proven acute rejection (BPAR), graft failure, and the development of de novo donor-specific antibodies was analyzed through univariate and multivariate models. Propensity score matching (PSM) was utilized to ensure a balanced comparison between the two groups. Following PSM, a total of 131 cases in the OKT group and 26 cases in the RAKT group were analyzed.
resultsAfter PSM, the mean recipient age was 48.56 years for OKT and 47.96 years for RAKT. Both groups had comparable one-year (RAKT: 92.4%, OKT: 93.1%) and two-year BPAR-free survival rates (RAKT: 92.4%, OKT: 91.9%). Mean estimated glomerular filtration rate values were similar at 12 months post-transplant (RAKT: 62.15 ml/min/1.73 m², OKT: 64.53 ml/min/1.73 m²). Operative times were significantly longer for RAKT (291.42 vs. 150.81 min, p < 0.001), while cold ischemic time was also longer for RAKT (119.77 vs. 47.22 min, p < 0.001). Hospital stays were shorter for RAKT (median 6 vs. 8 days, p < 0.001). There was no significant difference in the composite outcome of BPAR, graft failure, and de novo donor-specific antibodies between the two groups (HR 0.858, 95% CI: 0.180-4.096, p = 0.848).
conclusionsRAKT is a safe and effective alternative to OKT in ABOi patients, demonstrating similar perioperative outcomes, graft survival rates, and renal function. The application of ropensity score matching analysis strengthens the reliability of these findings, confirming RAKT's viability for high-risk kidney transplant recipients.
