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 compare the efficacy, safety, and factors influencing the outcomes of trabeculectomy (TE), conventional canaloplasty (cCP), and mitomycin C augmented canaloplasty (mCP) in glaucoma patients.
methodsIntraocular pressure (IOP), the number of IOP-lowering eye drops, and surgery-related complications were evaluated at baseline and through 18 months postoperatively. Correlations between patients' demographic data, ophthalmic and non-ophthalmic conditions, outcomes and complications were evaluated.
results171 patients were included. IOP and IOP-lowering eye drops were significantly (p < 0.001) reduced 18 months after TE, cCP, and mCP. At the 18-month follow-up, IOP and IOP-lowering eye drops were significantly lower following TE than cCP (p < 0.001, p = 0.010, respectively) and mCP (p = 0.010, p = 0.014). At the 18-month follow-up, complete success rates were significantly higher after TE compared to cCP and mCP for IOP ≤ 21, 18, and 16 mmHg (p < 0.001). Qualified success rates for IOP ≤ 16 mmHg were higher following TE than cCP and mCP (p = 0.023). In the TE group, clinical hypotony at any postoperative follow-up was positively correlated with previous intravitreal anti-vascular endothelial growth factor (VEGF)-therapy (p < 0.001), leukaemia (p = 0.002), and a spherical equivalent < -3 dioptres (p < 0.001). There were no significant correlations in the cCP and mCP groups.
conclusionTE, cCP, and mCP led to a significant reduction in IOP and IOP-lowering eye drops during 18 months of follow-up. At 18 months of follow-up, IOP and IOP-lowering eye drops were significantly lower following TE compared to cCP and mCP. Anti-VEGF-therapy, cystostatic therapy in leukaemia, and a spherical equivalent < -3 dioptres were significantly correlated with postoperative hypotony, macular folds, and choroidal detachment in the TE group. KEY MESSAGES: What is known • Trabeculectomy (TE) is considered the gold standard in the surgical management of glaucoma. However, TE involves extensive postoperative management and might be associated with severe surgery-related complications. What is new • In this study, intraocular pressure (IOP) and IOP-lowering eye drops were significantly lower following TE compared to conventional canaloplasty (cCP) and mitomycin C augmented canaloplasty (mCP) at a follow-up of 18 months. • In patients undergoing TE, anti-VEGF-therapy, cystostatic therapy in leukaemia, and a spherical equivalent < -3 dioptres were significantly correlated with postoperative hypotony, macular folds, and choroidal detachment.
