Impact of donor-recipient gender mismatch on outcomes in Descemet membrane endothelial keratoplasty (DMEK).

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
purposePrevious studies have suggested that H-Y antigens may influence immunological outcomes in corneal transplantation. This study analyses the influence of donor-recipient gender mismatch in DMEK on postoperative outcomes.
methodsThis single-center retrospective study included 2521 eyes (1712 patients) that underwent DMEK between January 2012 and December 2021. Patients were divided into four groups according to donor-to-recipient gender combinations (male-to-female, male-to-male, female-to-male, female-to-female) and were compared in terms of graft failure rate, visual acuity (VA), central corneal thickness (CCT), and endothelial cell count (ECC) preoperatively and at 1, 12 and 36 months postoperatively, as well as in terms of postoperative complications.
resultsOf the 2521 cases, 1647 (65%) were sex-mismatched (male-to-female or female-to-male) and 874 (35%) were sex-matched (female-to-female or male-to-male). Intraoperative preparation time of the grafts (p = 0.78) and difficulties in the intraoperative handling (p = 0.43) were comparable in all groups. Re-bubbling or re-keratoplasty was required with comparable frequency (p = 0.84; p = 0.61 respectively). The occurence of primary or secondary graft failure was not statistically significant different between the groups (p = 0.57). No confirmed case of immunological graft rejection occurred. Functional postoperative outcomes for ECC (p = 0.18 after 1 month, p = 0.13 after 12 months, p = 0.27 after 36 months), CCT (p = 0.58 after 4-6 weeks, p = 0.82 after 12 months, p = 0.78 after 36 months) and VA (p = 0.64 after 4-6 weeks, p = 0.47 after 12 months, p = 0.39 after 36 months) were comparable in all groups at the follow-up.
conclusionsIn this retrospective cohort, no documented immune graft rejection was observed, and sex mismatch did not influence intraoperative handling or postoperative interventions. However, prospective studies with standardized immunologic assessment are needed to clarify the role of donor-recipient sex mismatch in DMEK outcomes.
