Non-penetrating deep sclerectomy with the sub flap (Ahmed's) suture: a 12-month comparative study.
Trial report in Eye (London, England), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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 assess the IOP-lowering effect of adding a mattress suture (Ahmed's suture) to non-penetrating deep sclerectomy (NPDS), in patients with open angle glaucoma over a 12-month follow-up period.
methodsThis is a randomized controlled study comparing 52 eyes with a sub-flap Ahmed's suture modified NPDS (group A) and 51 with a conventional NPDS (group B). Success of surgery was categorized as complete success if the IOP remained between 6 and 18 mmHg without medications and as qualified if topical medications were required.
resultsThe post-operative IOP at the 1st week, 3rd, 6th, 9th & 12th months follow ups in group A were significantly lower (7.3 ± 2.1, 12.0 ± 2.3, 12.6 ± 2.7, 13.6 ± 3.4 & 13.8 ± 3.8 mmHg) than in B (9.2 ± 1.9, 14.0 ± 3.1, 14.8 ± 2.9, 15.4 ± 2.6 & 15.7 ± 2.7 mmHg) (p = 0.001, p = 0.001, p = 0.002, p = 0.027 & p = 0.029 respectively). The percentage of IOP reduction after 1 year was significantly higher in group A than in group B (49% vs. 36.5%). At the end of the 12-month follow-up, 81% of group A and 69% of group B were considered as complete success. Multivariate regression analysis showed lower 1st week post-operative IOP was associated with better outcome.
conclusionIn conclusion, the Ahmed's suture, a simple, novel and economic modification, maintains lower IOP levels and has a higher success rate over conventional DS, as it is 30% more effective in reducing the IOP.
