Combined versus Sequential Surgery in Lamellar Macular Holes: A Multicenter Observational Study.
Article in Clinical ophthalmology (Auckland, N.Z.), 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
Purpose: To compare 1-year best-corrected visual acuity (BCVA) after pars plana vitrectomy (PPV) for lamellar macular hole (LMH) between combined phacovitrectomy and sequential strategies, and to explore factors associated with postoperative visual outcome. Methods: Multicenter observational study of adults with optical coherence tomography (OCT)-confirmed LMH undergoing PPV. Surgical sequence was classified as combined surgery or sequential surgery (PPV→phacoemulsification, PPV in pseudophakic eyes, or PPV without subsequent cataract extraction). LMHs were classified as tractional, mixed, or degenerative based on OCT criteria. BCVA (logMAR) was recorded preoperatively and at 1 year. Ceiling effect was defined as achieving 1-year BCVA ≤0.22 logMAR. Independent predictors of 1-year BCVA were assessed using a linear mixed-effects model with a random intercept for patient. Results: A total of 175 eyes from 167 patients were included; 1-year BCVA was available for 126 eyes (72.0%), whereas 49 eyes (28.0%) had missing 1-year BCVA. Among eyes with recorded 1-year BCVA, no statistically significant differences were detected between combined and sequential surgery (0.2 [0.1-0.3] vs 0.2 [0.1-0.3]; p = 0.939) or among LMH subtypes. Overall, BCVA improved from 0.4 (IQR 0.3-0.5) to 0.2 (0.1-0.3) at 1 year. In ceiling-effect analysis, baseline BCVA (p = 0.013) and the presence of isolated epiretinal membrane (p = 0.032) were associated with achieving BCVA ≤0.22 logMAR. In the mixed-effects model, baseline BCVA was the only independent predictor of 1-year BCVA (β = 0.60; 95% CI 0.32-0.89; p < 0.001). Conclusion: PPV for LMH was associated with visual improvement at 1 year, and the study did not detect statistically significant differences in final BCVA between combined and sequential strategies or among LMH subtypes. Baseline BCVA was the main determinant of 1-year outcomes, supporting individualized selection of surgical sequence based on lens status and shared patient-surgeon preferences.
