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

backgroundWe performed a meta-analysis to determine the impact of mild, moderate, and severe visual field loss on quality of life (QoL) in patients with glaucoma.

methodsA comprehensive literature search was performed using the PubMed, Excerpta Medica dateBASE and China National Knowledge Infrastructure databases to identify relevant articles published before June 30, 2016. Patients' QoL was measured using the Glaucoma Quality of Life-15 Questionnaire (GQL-15).

resultsIn total, 401 patients with glaucoma and 205 patients without glaucoma participated in 4 experiments. The GQL-15 summary scores are statistically different between patients with and without glaucoma (standard mean difference [SMD] = 0.94, 95% confidence interval [CI]: 0.73-1.16, P < .01). GQL-15 summary scores for patients with mild, moderate, and severe visual field loss all differed significantly from those of patients without glaucoma; the SMDs for their summary scores were as follows: mild: 1.24, 95% CI: 0.26 to 2.22, P = .01; moderate: 2.05, 95% CI: 0.91 to 3.19, P < .001; and severe: 2.57, 95% CI: 1.44 to 3.71, P < .001. Two factor scores for central and near vision (SMD = -0.35, 95% CI: -1.01 to 0.30, P = .29) and glare and dark adaptation (SMD = -0.36, 95% CI: -1.01 to 0.30, P = .28) did not differ significantly between patients with mild and moderate visual field loss. However, summary scores and 2 factor scores (peripheral vision and outdoor mobility) differed significantly between patients with mild and moderate glaucoma. In addition, summary scores and all 4 factor scores differed significantly between patients with mild and severe glaucoma. Moreover, summary scores and 3 factor scores (peripheral vision, glare and dark adaptation, and outdoor mobility) differed significantly between patients with moderate and severe glaucoma. However, scores for 1 factor (central and near vision) did not differ significantly between any of the patient groups (SDM = -0.53, 95% CI = -1.33 to 0.27, P = .19).

conclusionsGlaucoma patients with visual field loss showed significantly poorer QoL relative to that of patients without glaucoma. Patients' QoL decreased as their glaucoma severity increased.
