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
purposeTo describe and evaluate an ophthalmic viscosurgical device (OVD)-assisted press injection technique for stabilizing a sectorial inverted internal limiting membrane (ILM) flap in full-thickness macular hole (MH) surgery without perfluorocarbon liquid or endotamponade.
methodsTwenty-eight eyes (28 patients) with full-thickness MH underwent 27-gauge pars plana vitrectomy with a superior sectorial inverted ILM flap. An OVD was first placed over the MH before indocyanine green (ICG) staining to minimize direct dye exposure to the fovea. After ILM flap creation, gentle OVD press injection was performed to flatten and secure the inverted flap over the hole. Postoperative outcomes included best-corrected visual acuity (BCVA), macular hole closure on optical coherence tomography (OCT), and surgical complications.
resultsAll surgeries were completed successfully using the OVD-assisted press injection technique. Anatomical closure of the macular hole was achieved in all eyes (100%). OCT demonstrated stable ILM flap coverage throughout follow-up. Mean BCVA improved significantly from 0.92 ± 0.29 log MAR preoperatively to 0.60 ± 0.29 log MAR at 3 months postoperatively (P < 0.001). No retinal detachment, MH reopening, or clinical evidence of ICG-related toxicity occurred. Intraocular pressure remained stable; transient hypotony occurred in two eyes and resolved within 1 week.
conclusionOVD-assisted press injection provides reliable mechanical stabilization of the inverted flap and enables macular hole closure without the need for perfluorocarbon liquids or endotamponade. CLINICAL TRIAL NUMBER: Not applicable.
