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 investigate predictors of discordance between symptoms and signs in dry eye disease (DED).

designCross-sectional association study.

participantsA total of 648 patients with dry eye from the Groningen LOngitudinal Sicca StudY (GLOSSY), a tertiary dry eye clinic patient cohort from the Netherlands.

methodsPatient symptoms were assessed using the Ocular Surface Disease Index (OSDI) questionnaire. Dry eye signs were assessed by tear osmolarity, Schirmer test, tear breakup time, corneal and conjunctival staining, and meibomian gland dysfunction, all in both eyes, and a composite dry eye signs severity score was calculated from these 6 tests for each patient. Linear regression analysis was used to test the association of discordance between symptoms and signs with a wide range of independent variables (demographic and environmental variables, systemic diseases, ocular traits, and medications).

main outcome measuresPredictors of discordance between symptoms and signs in DED, defined by the difference between the rank score of the OSDI and the rank score of the dry eye signs severity score.

resultsOf the 648 subjects in this cohort, 536 (82.7%) were female and the mean age was 55.8 years (standard deviation, 15.6 years). Significant predictors of greater symptoms than signs were the presence of a chronic pain syndrome, atopic diseases, a known allergy, the use of antihistamines (all P < 0.001), depression (P = 0.003), osteoarthritis (P = 0.008), and the use of antidepressants (P = 0.02). Predictors of lesser symptoms than signs were increased age (P < 0.001) and the presence of Sjögren's disease (P < 0.001) (primary Sjögren's disease, P < 0.001) more than secondary Sjögren's disease (P = 0.08), and graft-versus-host disease (P = 0.04). Furthermore, greater symptoms compared with signs were highly associated with lower self-perceived health (P < 0.001).

conclusionsThis large clinical study has shown that discordance between symptoms and signs in DED is an indicator of self-perceived health. The study found important predictors of greater symptoms to signs but also predictors of lesser symptoms to signs. Awareness of these predictors is helpful in assessing patients with dry eye in clinical practice.
