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 compare dry eye symptoms and findings in post cataract surgery eyes' with and without preexisting dry eye. STUDY

designProspective, observational case-control study.

methodsSixty-seven eyes that had undergone cataract surgery were included; 48 were classified into group D (preexisting dry eye) and 19 into group N (no preexisting dry eye). No subjects received perioperative treatment for dry eye. We evaluated between-group differences in symptom scores, corrected distance visual acuity (CDVA), tear film breakup time (BUT), tear film breakup pattern (BUP), and ocular surface fluorescein staining scores, at 1 week, 1 month, and 3 months postoperatively.

resultsSymptoms were unchanged in group N, but improved in group D (P < .001) postoperatively. CDVA was improved after surgery in both groups (P < .001). BUT was shorter preoperatively in group D than in group N although this difference was absent 1 month postoperatively. Fluorescein staining scores significantly increased at 1 month postoperatively in group N (P = .01), but did not change in group D. During the perioperative period, the predominant BUP was the random break pattern in both groups (≥ 85%). From 1 week to 3 months, dimple break patterns decreased in group D (P = .007), whereas spot break patterns increased (P = .01).

conclusionsCataract surgery has an influence on tear film stability and the ocular surface. There was either a transient improvement or worsening of ocular surface wettability in some patients without preexisting dry eye.
