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
Purpose: This study aimed to compare clinical characteristics and treatment patterns between patients with normal tension glaucoma (NTG) and preperimetric glaucoma (PPG), assess medication trends over time, and benchmark these against a 2020 study to inform treatment strategies. Materials and Methods: During March 10-16, 2024, 6323 outpatients diagnosed with glaucoma or ocular hypertension were enrolled in a survey conducted across 82 private practices. We compared patient characteristics and medication usage between those with NTG and PPG. Results: Among the enrolled patients, 2882 were diagnosed with NTG, and 344 were diagnosed with PPG. The average age was significantly lower in the PPG group (60.2 ± 14.3 years) than in the NTG group (69.0 ± 12.9 years, P < 0.0001). The average number of medications used was significantly higher for the NTG group (1.7 ± 1.1 drugs) than for the PPG group (0.4 ± 0.7 drugs; P < 0.0001). Monotherapy was used in 1473 patients with NTG and 96 patients with PPG. The most prescribed medications were prostanoid FP receptor agonist (FP agonists) (61.6% and 47.9% for NTG and PPG, respectively), β-adrenergic blockers (β-blockers) (18.3% and 27.1% for NTG and PPG, respectively), and prostanoid EP2 receptor agonist (EP2 agonists) (12.4% and 14.6% for NTG and PPG, respectively). FP agonist prescriptions were significantly more common in patients with NTG than in patients with PPG (P < 0.05). β-blockers and ion channel opener prescriptions were significantly more common in patients with PPG than in patients with NTG (P < 0.05). FP/β fixed-combination eye drops were the most prescribed treatment for both groups. These were used in 399 patients with NTG and 10 patients with PPG. Conclusion: NTG was more prevalent than PPG in this population. Patients with PPG were significantly younger and required fewer medications compared to those with NTG.
