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 is aimed at reporting a rare case of polygonal retinal pigment epithelium (RPE) avulsion following retinal cryotherapy for retinal detachment. Methods: Case report. Results: A 53-year-old man presented with recurrent retinal detachment 30 days after 23G vitrectomy with 20% sulfur hexafluoride (SF6) gas endotamponade. Intraocular pressure was < 1 mmHg, with horizontal chorioretinal folds due to hypotony. Re-vitrectomy with PFCL, cryotherapy, endolaser, and silicone oil was performed. During surgery, a large RPE avulsion with island formation and a small full-thickness retinal avulsion causing re-detachment were identified in the cryotherapy area. After 6 months with attached retina, the silicone oil was removed and the retina remained stable. Conclusions: Cryotherapy-induced scarring for retinal detachment repair is likely to cause traction. In our case, traction from the scar resulted in a full-thickness retinal tear and RPE avulsion, leading to re-detachment. Careful follow-up is essential to detect and treat complications.
