Three-year Outcomes of Endothelial Keratoplasty in Late-Stage Elderly Versus Younger Patients.
Observational study in Clinical interventions in aging, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Purpose: This study aimed to report the 3-year clinical outcomes of corneal endothelial keratoplasty (EK) in late-stage elderly patients (≥75 years) compared with younger patients (<75 years). Study Design: Retrospective observational study. Methods: Patients who underwent EK, including Descemet's stripping automated keratoplasty (DSAEK) and non-Descemet stripping and automated endothelial keratoplasty (nDSAEK) with bullous keratopathy (BK) at Keio University Hospital between 2016 and 2018, were included. Patient characteristics, graft survival rate, best corrected visual acuity (BCVA), corneal endothelial cell density (ECD), and complications were compared between the late elderly group (75 years or older) and the younger group (<75 years old) stratified by surgical procedure. Results: Among the 64 eyes and 55 patients who underwent EK, 31 eyes and 30 patients were in the late elderly group (81.4±3.7 years), and 33 eyes and 25 patients were in the younger group (66.2±9.1 years). There was no difference between the groups in terms of the cause of BK, and PBK was more common in the DSAEK group in the late elderly group (p = 0.029). There was no difference in graft survival between the two groups during the follow-up period. In the late elderly group, graft survival was significantly better in the nDSAEK group than in the DSAEK group (p = 0.045). BCVA and postoperative ECD improved in both groups. There were no differences in intraoperative or postoperative complications between the late elderly and younger groups. Conclusion: EK for BK in late elderly patients resulted in postoperative visual improvement, with similar efficacy and safety to those of EK for BK in younger patients.
