Preservative-Free versus Benzalkonium Chloride-Preserved Latanoprost Ophthalmic Solution in Patients with Primary Open-Angle Glaucoma or Ocular Hypertension: A Phase 3 US Clinical Trial.

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 safety and efficacy of a preservative-free latanoprost 0.005% formulation (T2345) in patients with primary open-angle glaucoma (POAG) or ocular hypertension (OHT) compared to benzalkonium chloride-preserved latanoprost 0.005% (BPL) formulation in the United States (US). Patients and Methods: A prospective, randomized, multicenter, observer-masked, parallel-group study enrolled 335 patients diagnosed with POAG or OHT from 31 US sites who had adequately controlled intraocular pressure (IOP; ≤18 mm Hg) with latanoprost monotherapy. After a ≥72-hour washout period, patients were randomized to T2345 (n=165) or BPL (n=170) groups. Study drugs were dosed once-daily from Day 0 to Day 84 in one or both eyes. The study eye was the eye with lower IOP at baseline. The primary efficacy measure was the between-group comparison of the mean IOP values in the study eye at each time point (8 AM, 10 AM, and 4 PM on Days 15, 42, and 84). Safety measurements included ocular and systemic treatment-emergent adverse events (TEAEs). Results: Both T2345 and BPL adequately controlled IOP with 95% CIs within 1.5 mm Hg in the study eye at all assessed time points. The percentages of patients with diurnal IOP <18 mm Hg at Day 84 were 73.1% vs 78.7% for the T2345 and BPL groups, respectively. Adverse events were generally mild-to-moderate and primarily ocular. Fewer patients in the T2345 group experienced ocular TEAEs (13.9% vs 22.5%, respectively) and TEAEs with a suspected relationship to the study medication compared with the BPL group (5.5% vs 11.8%, respectively). The most common ocular TEAEs were instillation site pain and conjunctival hyperemia. Conclusion: In patients with POAG or OHT, both T2345 and BPL maintained IOP at or below clinically meaningful values for the duration of the study. T2345 showed a favorable safety profile, with numerically lower incidences of ocular TEAEs than BPL.
