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

objectiveTo investigate the dry eye symptoms after cataract surgery in MGD patients and their relationships

methodsThe study included 115 patients (115 eyes) with age-related cataract that underwent uncomplicated cataract surgery, and the patients were divided into two groups according to the MGD diagnostic criteria: group A (MGD group) and group B (control group). Schirmer I test (ST-I), tear breakup time (TBUT), and corneal fluorescein staining (CFS) were performed preoperatively and at 3 days, 7 days, 14 days, and 30 days postoperatively. We also measured eyelid meibomian gland morphology, meibomian gland expression, and meibum character scores before and after the cataract surgery.

resultsPostoperatively, in group A, TBUT decreased and CFS scores increased significantly. ST-I increased in the early postoperative course but decreased later. The eyelid margin morphology scores and meibomian gland expression scores of group A significantly increased after the cataract operation. Thus, patients with MGD may have a greater chance of developing the dry eye disease after cataract surgery. Cataract surgery may aggravate the signs of MGD, and the severity of MGD may positively correlate with TBUT, CFS, and corneal lesions after surgery.

conclusionsThe characteristics of dry eye after cataract surgery in patients with MGD are different from common cataract patients, changes in the early postoperative phase to the ocular surface were caused by surgical factors, and the damages to epithelial function in the later postoperative phase were mainly associated with the inflammation of the meibomian gland and eyelid.
