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

BACKGROUND/

aimsTo examine the profile of diabetic retinopathy, awareness and self-help in patients attending a specialist eye clinic in Hangzhou, China.

methodsA total of 199 consecutive patients with diabetes (mean age = 57 years, SD = 11) attending eye clinic at the School of Medicine, Zhejiang University, Hangzhou were examined in a cross-sectional study. Clinical/demographic data were obtained from patients' records. Fundus photographs obtained from each patient were graded using Early Treatment of Diabetic Retinopathy Study (ETDRS) criteria; severe non-proliferative, proliferative retinopathy and/or macular oedema (hard exudates/thickening around fovea) were classified as sight-threatening diabetic retinopathy (STDR). Optical coherence tomography was used to confirm the diagnosis of macular oedema. Data on knowledge/awareness about diabetes and self-help/lifestyle were collected using a structured questionnaire.

resultsSTDR was found in 80% patients of whom 18% had visual acuity of ≤counting fingers in at least one eye. Male gender, longer diabetic duration and use of insulin were significantly associated with STDR (p ≤ 0.05). Of the total, 41% patients reported that they were attending for the first time. Of all the first-time attendees, 67% had STDR. Also of all the first-time attendees, 14% were unclear whether diabetes affected their eyes. Fifty-one per cent of patients who thought their diabetes was well controlled had fasting blood sugar ≥6.5 mmol/L (p < 0.001). Of the total, 65% patients reported not doing ≥4 hours/week of physical exercise.

conclusionsThe majority of patients with diabetes presented to this eye clinic suffered with late-stage retinopathy. Our results advocate the need to improve diabetic diagnosis, management and awareness and to set up eye screening for diabetics in Hangzhou, China.
