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
Background: This study aimed to evaluate the 2-year outcomes of modified external suture trabeculotomy in the treatment of open-angle glaucoma (OAG) among Chinese patients. Methods: A retrospective study was designed, involving 138 OAG patients (138 eyes) treated with modified external suture trabeculotomy at the First Affiliated Hospital of Nanjing Medical University from January 2020 to June 2023. The patients were followed up at 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years. Surgical success was defined as intraocular pressure (IOP) ≤ 21 mmHg (1 mmHg = 0.133 kPa) under glaucoma medication (conditional success) and without any glaucoma medication (complete success). The main outcomes were measured according to IOP, number of medication regimens, surgical success rate, and complications. Results: A total of 138 OAG patients (138 eyes) were included, with a mean age of 58.57 ± 13.66 years (range, 25-86 years). The mean postoperative IOP decreased from preoperative 24.59 ± 9.82 to postoperative 15.50 ± 6.49, 15.70 ± 5.76, 14.36 ± 3.59, 14.49 ± 3.96, 14.71 ± 4.31, and 14.31 ± 3.16 mm Hg at 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years, respectively. The mean numbers of medication regimens were 2 (0 ~ 4), 0 (0 ~ 3), 0 (0 ~ 3), 0 (0 ~ 3), 0 (0 ~ 2), 0 (0 ~ 3), 0 (0 ~ 3) at the seven time points, respectively. The mean postoperative IOP and the number of medication regimens at each time point were significantly lower than those before the operation (all Conclusion: Simple and cost-effective, the modified external suture trabeculotomy provides favorable 2-year outcomes in treating medically uncontrolled OAG, as shown by short surgical duration, effective IOP control, significant drug reduction, and fewer postoperative interventions.
