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

backgroundTo evaluate the safety and efficacy of a bandage contact lens for alleviating dry eye discomfort after phacoemulsification.

methodsIn this prospective, controlled study, 60 age-related cataract patients with mild Meibomian gland dysfunction (MGD) were randomized to treatment with an ocular bandage contact lens (BCL) (n = 30) or to an untreated control group (n = 30) after phacoemulsification and intraocular lens implantation. The Ocular Surface Disease Index (OSDI) questionnaire, evaluation of subjective symptoms and evaluation of the best-corrected visual acuity (BCVA) were conducted preoperatively and postoperatively on days 1, 7, 14, 30 and 90. The tear breakup time (TBUT), Schirmer test with anesthesia, and fluorescein staining scores were measured preoperatively and postoperatively on days 7, 14, 30 and 90.

resultsThere were no significant differences with respect to the BCVA between the groups at any time point. For the comparison of the OSDI, subjective evaluation scores, TBUT and fluorescein staining, statistically significant improvements were noted in the BCL group, especially on days 7 and 14 (P < 0.001, P < 0.001; P = 0.031, P = 0.009; P = 0.021, P = 0.028; and P = 0.03, P = 0.032, respectively). The Schirmer test results did not significantly change postoperatively.

conclusionsA BCL can improve tear film stability and lessen dry eye discomfort immediately after phacoemulsification.
