Comparison of the efficacy of latanoprost versus dorzolamide/timolol fixed combination therapy in patients with pseudoexfoliative glaucoma according to glaucoma stage.
Article in Arquivos brasileiros de oftalmologia, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeOnly a few trials have compared the intraocular pressure-lowering effects of prostaglandin analogs to carbonic anhydrase inhibitor plus beta-blocker fixed-dose combination therapy in patients with pseudoexfoliative glaucoma. Furthermore, the influence of the glaucoma stage on the intraocular pressure-lowering effects of these drug types has not been studied. The purpose of this study was to compare the IOP-lowering efficacy of latanoprost, a prostaglandin analog versus dorzolamide/timolol fixed combination, a carbonic anhydrase inhibitor plus beta-blocker fixed-dose combination therapy, in patients with pseudoexfoliative glaucoma based on glaucoma stage.
methodsThe data of 32 eyes (32 patients) diagnosed with uniocular pseudoexfoliative glaucoma and treated with topical latanoprost (Group 1) or dorzolamide/timolol fixed combination (Group 2) were retrospectively assessed. The groups were subdivided into early and moderate-advanced stages. Patients' demographics, baseline intraocular pressure, final intraocular pressure, and intraocular pressure difference (the difference between the baseline and final intraocular pressure) were determined from medical records and compared between groups and according to glaucoma stage.
resultsThe mean drug use duration was 17.7 ± 13.5 months. No significant differences in mean baseline intraocular pressure, mean final intraocular pressure and mean intraocular pressure difference between Groups 1 and 2. In Group 2, the mean intraocular pressure difference was significantly greater in patients with early versus moderate-advanced stage glaucoma (p=0.015). The difference, however, was not detected in Group 1. The mean intraocular pressure difference in early-stage glaucoma was significantly greater in Group 2 versus 1 (p=0.033).
conclusionsLatanoprost and dorzolamide/timolol fixed combination are effective treatments for newly diagnosed pseudoexfoliative glaucoma. In early-stage pseudoexfoliative glaucoma, greater intraocular pressure reduction was noted with dorzolamide/timolol fixed combination than with latanoprost; thus, dorzolamide/timolol fixed combination should be considered when a significant decrease in intraocular pressure is desired in early-stage glaucoma.
