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

backgroundProlonged use of visual display terminal images on electronic devices such as computers frequently leads to symptoms of dry eye. Tear substitutes form the mainstay of treatment for mild-to-moderate dry eye.

aimThe study aimed to evaluate the efficacy and safety of carboxymethyl cellulose (CMC) versus hydroxypropyl methylcellulose (HPMC) tear substitutes for dry eye due to computer vision syndrome (CVS). MATERIALS AND

methodsThis was a prospective, randomized, comparative, and open-labeled study. The efficacy of CMC 0.5% and HPMC 0.3% tear substitutes was compared in 180 participants (90 in each group) with dry eye. Change in Ocular Surface Disease Index (OSDI) score, Schirmer I test score, and tear film break up time (TF-BUT) were used as efficacy parameters. Safety was monitored on all visits.

resultsThe baseline OSDI score? 23.48 and 23.32 in Group A and B, respectively, decreased with treatment in both groups on all follow-up visits as compared to the baseline (day 90: 13.9 ± 3 vs. 14.81 ± 3.17,

conclusionCMC and HPMC tear substitutes were equally efficacious and safe in reducing symptoms of dry eye due to CVS.
