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 describe the surgical technique and evaluate the preliminary short-term outcomes of penetrating keratoplasty (PKP) combined with intrascleral fixation of a four-haptic intraocular lens (IOL) in aphakic eyes with corneal pathology and insufficient capsular support. Methods: This prospective case series included five consecutive patients who underwent combined PKP and intrascleral fixation of a four-haptic IOL. Four eyes had bullous keratopathy with aphakia, and one had traumatic corneal leukoma with aphakia. Best-corrected visual acuity (BCVA), intraocular pressure (IOP), graft clarity, corneal endothelial cell density (ECD), IOL position, and complications were assessed over at least 6 months. Results: Mean BCVA improved from 3.00 ± 0.00 logMAR preoperatively to 1.04 ± 0.14 logMAR at 6 months ( Conclusion: Combined PKP and intrascleral fixation of a four-haptic IOL appears to be a feasible single-stage option for selected aphakic eyes with corneal pathology and insufficient capsular support. Favorable short-term anatomical and visual outcomes were observed, but the small sample size, lack of control group, and short follow-up limit generalizability. Larger comparative studies with longer follow-up are needed.
