1 · What the graph read from it

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.

2 · The registry

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

backgroundPrimary open-angle glaucoma (POAG), often associated with increased intraocular pressure (IOP), can lead to permanent damage of the optic nerve, concomitant visual field loss, and blindness. Latanoprost, a prostaglandin F2α analogue, reduces IOP and is used to treat glaucoma. In this clinical trial, we evaluated the efficacy of Latanoprost Polpharma, a generic preservative-free latanoprost 0.05 mg/ml eye drops solution, in lowering IOP when compared to the originator Xalatan

methodsThis was a Phase III, multicentre, randomized, investigator-masked, cross-over, comparative, non-inferiority trial carried out in 5 sites in Hungary and Russia. The primary endpoint was to evaluate the non-inferiority of the test product when compared to the reference product with respect to the differences in the mean diurnal IOP on Day 1 (baseline) and Day 29. The secondary endpoints included efficacy, ocular tolerance, safety, and usability. We recruited adult patients (18-75 years) with open-angle glaucoma or ocular hypertension.

resultsForty-nine patients were randomised and received at least one dose of the test or reference product. A virtually identical reduction of the mean diurnal IOP of 7.04 ± 2.14 mmHg or 7.17 ± 2.11 mmHg was found after treatment with test or reference product, respectively (N = 44). In the intention to treat analysis, the reduction was 7.29 ± 2.53 mmHg (95% CI: 6.55-8.04) or 7.43 ± 2.78 mm Hg (95%CI: 6.61-8.24) after treatment with test or reference product, respectively (N = 47). There were no serious adverse events.

conclusionsLatanoprost Polpharma was shown to be non-inferior to Xalatan

trial registrationThe study had the ethical and regulatory approval from the National Institute of Pharmacy and Nutrition (OGYEI, OGYEI/41,779- 11/2018) and the Ethics Committee for Clinical Pharmacology (KFEB) of Hungary and from the Ministry of Healthcare of the Russian Federation (MOH of Russia) prior to the beginning of the study (642/25.12.2018) (clinical trial identification number: 848,300,144/0103/1 - POP03; IND number/EudraCT number: 2018-001727-39).
