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

purposeTo observe morphological changes in the meibomian glands of patients with contact lens-related allergic conjunctivitis (CLAC) and to assess the relations between the morphological changes and eyelid and tear film parameters.

methodsWe observed subjects in four groups: 64 eyes of 64 contact lens (CL) wearers with CLAC, 77 eyes of 77 CL wearers without CLAC, 55 eyes of 55 patients with perennial allergic conjunctivitis (perennial AC), and 47 eyes of 47 healthy volunteers. The following tests were performed: slit-lamp examination, measurement of tear film breakup time, grading of morphological changes in meibomian glands (meiboscore) as assessed by noncontact meibography, grading of meibomian gland distortion in meibography, tear production as assessed by Schirmer's I test, and grading of meibum expression.

resultsThe mean score for meibomian gland distortion was significantly higher in the CL wearers with CLAC than in the CL wearers without CLAC (p < 0.0001); it was also significantly higher in the non-CL wearers with perennial AC than in the non-CL wearers without perennial AC (p < 0.0001). There was no significant difference between the mean scores for meibomian gland distortion of the non-CL wearers with perennial AC and the CL wearers with CLAC (p = 0.27). The score for meibomian gland distortion was significantly positively correlated with the meibum score in the CL wearers with CLAC and with the meiboscore in the CL wearers without CLAC.

conclusionCLAC is associated with an increase in meibomian gland distortion. Allergic reaction, rather than CL wear, appears to be responsible for the increase in meibomian gland distortion in patients with CLAC.
