Reevaluating Donor-recipient Sex Mismatch and Survival After Liver Transplantation: A Contemporary Cohort Study.
Article in Transplantation direct, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Identifying an optimally matched donor is a critical determinant of outcomes following liver transplantation (LT). Several donor- and recipient-related factors have been shown to influence posttransplant survival. However, the impact of donor-recipient sex mismatch (DRSM) on long-term outcomes remains controversial, with inconsistent findings reported across prior studies. This study aimed to further clarify the contemporary role of DRSM in LT outcomes. Methods: We conducted a single-center retrospective cohort study including 1146 adult patients who underwent LT at the Ajmera Transplant Centre, Toronto, between January 2014 and January 2022. Donor and recipient characteristics, including age, sex, and donor type, were analyzed. The primary outcome was patient survival up to 10 y of follow-up. Comparative analyses were performed between recipients with mismatch (DRSM+) and those without (DRSM-), as well as relevant subgroup analyses. Results: In unadjusted survival analysis, recipients in the DRSM+ group demonstrated slightly higher survival compared with DRSM- recipients up to 10 y following LT ( Conclusions: DRSM does not appear to be an independent risk factor for reduced long-term survival after LT. Moreover, the composition of favorable recipient and donor characteristics seems to be the main factors influencing long-term survival. These findings suggest that DRSM alone should not preclude donor selection in clinical practice.
