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

Purpose: To compare the lipid layer thickness (LLT) using the LipiView® ocular surface interferometer (TearScience® Inc, Morrisville, NC) between the eye treated with glaucoma medication and untreated normal eye in the unilateral glaucoma patients, and evaluate the effect of topical glaucoma medication on the LLT parameters in glaucoma eyes. Methods: The participants in this cross-sectional comparative study were unilateral glaucoma patients treated with topical glaucoma medications for more than 12 months. Three LLT parameters (average, minimum, and maximum) obtained by the LipiView® were compared between the glaucomatous eye and normal eye. The factors associated with LLT parameters in the eyes treated with glaucoma medication were investigated with multiple regression analysis. Results: Thirty patients with unilateral normal tension glaucoma were enrolled in the present study. Lipid layer average, minimum, and maximum were 64.83 ± 16.50, 51.63 ± 16.73, and 82.53 ± 20.62 in glaucomatous eyes, 77.26 ± 17.81, 62.83 ± 20.99, and 86.13 ± 15.42 in normal eyes. Lipid layer average and minimum were significantly thinner than those in normal eyes (P < 0.001, P < 0.001, respectively). Longer duration of glaucoma eye drops and a greater number of glaucoma medications were associated with the lower LLT average (β = -0.456, P < 0.001, β = -8.517, P = 0.003, respectively), and increasing glaucoma medications have a significant correlation with lower LLT minimum in glaucoma eyes (β = -8.814, P = 0.026). Conclusion: The present study highlights that patients with long-term glaucoma medications need to be assessed for LLT parameters objectively evaluate their ocular surface health.
