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
purposeThe Xen gel stent is a surgical glaucoma device which creates a subconjunctival filtering bleb, which has demonstrated good intraocular pressure (IOP) lowering and safety. Nonetheless, bleb-related problems have been reported. We present a case series of ab externo Xen procedures augmented with a deep intra-scleral lake, aiming to improve both IOP-lowering and post-operative management.
methodsA retrospective review of 20 patients who underwent combined Xen gel stent implantation with modified deep sclerectomy at our institution from June to November 2022, with a 6-month follow-up period. We reviewed demographics, past ocular history, visual acuity (VA), IOP, visual fields, glaucoma medication use, complications, and perioperative information.
results20 eyes of 20 patients, with a mean age of 67.45 ± 14.38 underwent surgery. Pre-operative initial IOP was 24.5 ± 7.96 mmHg, improving to 11.50 ± 2.96 mmHg at 6 months; a change of -12.89 ± 8.34 mmHg and a mean decrease of 51.13 ± 20.15% (p < 0.0001) Patients were on 3.1 ± 0.72 glaucoma medications pre-operatively, improving to 0.72 ± 1.27 at 6 months (p < 0.0001). Visual field mean deviation was -13.99 ± 9.98 dB pre-operatively and -10.27 ± 9.06 dB at 6 months, with VA of 0.287 ± 0.69 pre-operatively and 0.31 ± 0.76 LogMAR post-operatively. No patients required bleb needling. 2 patients underwent subsequent bleb revision surgery. 2 patients developed choroidal effusions, which were managed conservatively with good visual outcomes.
conclusionIn this preliminary study, we have found the modification of Xen gel stent implant surgery with a modified deep sclerectomy to offer good IOP lowering, with low rates of bleb needling and a good safety profile.
