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 evaluate the effect of trabecular meshwork strip peeling (TP) during hemi-gonioscopy-assisted transluminal trabeculotomy (hemi-GATT) on the frequency of early postoperative intraocular pressure (IOP) spikes and surgical success.
methodsThis retrospective study included 42 eyes of patients with primary open-angle or pseudoexfoliative glaucoma who underwent hemi-GATT with TP (n = 14) or standard hemi-GATT without TP (n = 28) at a tertiary glaucoma center. Hemi-GATT was intentionally selected as a planned primary surgical strategy and was not performed as a secondary procedure following failed circumferential GATT. An IOP spike was defined as postoperative IOP > 30 mm Hg or an increase of ≥ 10 mm Hg from the previous visit. Surgical success was defined as qualified (IOP ≤ 21 mm Hg and ≥ 30% reduction from baseline with or without medication) or complete (without medication). The primary outcome was the incidence and predictors of early IOP spikes; secondary outcomes included surgical success rates and related risk factors.
resultsAn IOP spike occurred in 11/42 eyes (26.2%) at 7.1 ± 4.8 days postoperatively, lasting 6.7 ± 5.1 days; mean peak IOP during spikes was 26.2 ± 5.0 mm Hg. All patients with an IOP spike experienced a decrease in IOP to ≤ 21 mm Hg within the first postoperative month. Spike frequency was lower with hemi-GATT + TP than with standard hemi-GATT (1/14 [7.1%] vs. 10/28 [35.7%]; p = 0.048). On multivariable analysis, higher baseline IOP increased spike risk (odds ratio [OR], 1.48; 95% CI, 1.08-2.01; P = 0.013), whereas TP reduced it (OR, 0.01; 95% CI, 0.01-0.38; P = 0.014). The mean follow-up period was 7.71 ± 2.03 months (range: 6-13 months). Qualified and complete success did not differ (92.9% vs. 89.3%, P = 0.769; 42.9% vs. 35.7%, p = 0.714).
conclusionTP during hemi-GATT significantly decreases early postoperative IOP spikes and enhances early IOP control, while maintaining surgical success.
