Tolerability in Glaucoma Patients Switched from Preserved to Preservative-Free Prostaglandin-Timolol Combination: A Prospective Real-Life Study.
Trial report in Clinical ophthalmology (Auckland, N.Z.), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Purpose: To evaluate the effect of switching from preserved prostaglandin analog-timolol fixed combinations (PG-timolol FCs) to preservative-free latanoprost-timolol FC (PF-LT) on intraocular pressure (IOP), ocular surface health, and tolerability in glaucoma and ocular hypertension (OH) patients with the concurrent ocular surface disease (OSD). Methods: This was a longitudinal, prospective, interventional, real-life study among 42 patients. Up to 3 visits were planned, at baseline, 30, and 90 days to assess efficacy on IOP decrease and local tolerance. The severity of OSD symptoms [Ocular Surface Disease Index (OSDI) questionnaire], subjective drug tolerability [visual analog scale (VAS)], conjunctival hyperemia (McMonnies scale), and tear break-up time (TBUT) were the main parameters assessed. Results: Data from 36 patients were available for statistical analysis. IOP was significantly reduced at day 30 and day 90 compared to baseline (16 vs 14 vs 14 mmHg, p < 0.001). Significant improvement was demonstrated in OSD symptoms, signs, and VAS scores from the baseline to the second and third visits. Median OSDI (27.1 vs 9.6 vs 4.2, p < 0.001), conjunctival hyperemia (2 vs 1 vs 1, p < 0.001), corneal surface staining (p < 0.001), and conjunctival staining scores (p < 0.001), and the percentage of patients with eyelid and periocular hyperemia (61.1 vs 12.5 vs 2.8%, p < 0.001), significantly decreased. TBUT (4 vs 5 vs 6 s, p < 0.001) and VAS score regarding tolerability (5 vs 2 vs 1, p < 0.001) significantly increased. Conclusion: A switch from preserved PG-timolol FCs to PF-LT improved tolerability and optimized IOP control, providing better adherence with greater chances of treatment success.
