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

introductionTo compare the tolerability and efficacy of a preservative-containing latanoprost (PCL) to a preservative-free formulation of latanoprost (PFL) in patients with open-angle glaucoma or ocular hypertension.

methodsA pooled analysis was performed of data from five published studies. The primary outcome was tolerability as evaluated by the severity of hyperemia. The secondary objectives were patient tolerance based on a composite ocular surface disease (OSD) score arising from ocular signs and symptoms, patient and investigator satisfaction, and a comparison of IOP-lowering efficacy.

resultsThere were three randomized controlled trials and two observational studies included in the analysis. Conjunctival hyperemia improved significantly in 25.6% (388) of patients switched to the PFL group versus 11.7% (117) of patients switched to the PCL group (p < 0.001). PFL was two times superior to PCL in reducing ocular hyperemia (odds ratio = 1.96; p < 0.001). The mean OSD composite score decreased by 32.2% in patients switched to the PFL group and 14.1% in the PCL group (p < 0.001). At 3 months, the mean IOP was similar between groups (p = 0.312).

conclusionThis post hoc pooled analysis confirmed the findings of the individual studies that PFL is as efficacious at reducing IOP as PCL but better tolerated. After switching to PFL, there was twice the improvement in the OSD composite score. PFL was twice as effective at reducing ocular hyperemia and other ocular signs. These findings suggest that PFL has features that may improve patient compliance, thereby potentially improving the IOP-lowering efficacy on a long-term basis.
