Cataract extraction after deep sclerectomy and its effect on intraocular pressure control.

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 estimate the incidence and predisposing factors for cataract extraction (CE) after Deep Sclerectomy (DS) with Mitomycin-C (MMC) and its effect on intraocular pressure (IOP) control.
methodsRetrospective study of phakic eyes which had DS with MMC performed over a 5-year period. 179 eyes of 179 patients were included.
resultsMean age at time of DS was 68.6 ± 9.7 years and mean follow-up was 89.4 ± 29.4 months. 63 eyes had CE and the probability of CE following DS was 0% at 1, 11.6% at 3, 21.0% at 5 and 33.2% at 7 years, with a 50% probability (median survival time) of 10 years. Age was association with increased risk for CE (Hazard ratio 1.05, 95% CI: 1.03-1.08, p < 0.0001). Mean IOP had increased from 11 mmHg to 15 mmHg in the first 3 months and remained higher up to a year (p < 0.001). There was no difference in the probability of maintaining an IOP < 16 mmHg without additional medications or needle revision (p = 0.05,Log-rank test). 20/47 eyes that failed were from the CE group, of which 14 (22.2%) failed prior to CE. Number of eyes on glaucoma medications before CE was 6 (mean edications 0.2 ± 0.5 m) and by last follow-up, 9 eyes were on medications (mean medications 0.2 ± 0.7). Post-CE needle revision was performed on 4 eyes.
conclusionsThe probability of CE after DS is low, with a gradual increase with time. Increasing age was found to be a statistically significant risk factor. There was a modest increase in IOP after CE and increase use of glaucoma medications.
