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 a modification of the Yamane double-needle technique using partial-thickness scleral groove-flap coverage of the terminal haptic flanges for secondary IOL implantation in eyes without adequate capsular support. Methods: This surgical technique report describes a modified approach to flanged intrascleral haptic fixation (ISHF). At two fixation sites 180° apart, partial-thickness scleral grooves are created. After haptic externalization and cauterization, the terminal flanges are guided into the grooves and buried beneath scleral tissue rather than positioned directly beneath the conjunctiva. Results: The technique was successfully performed in three eyes requiring secondary IOL implantation without adequate capsular support. At 12 months postoperatively, all patients demonstrated stable IOL centration with complete conjunctival epithelialization over the haptic sites. No cases of haptic exposure, endophthalmitis, or flange-related irritation were observed. Conclusion: The scleral groove-flap modification preserves the essential workflow of the Yamane technique while providing additional scleral tissue coverage over the terminal haptic flanges. In this small case series without a comparison group, the technique was associated with stable IOL centration, complete conjunctival epithelialization, and no observed haptic exposure during 12 months of follow-up.
