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

objectiveThe aim of this study was to assess the prevalence of diabetic retinopathy (DR) and retina screening coverage among people with diabetes in the catchment area of a high-volume eye care organisation in north India.

designA population-based cross-sectional study using Rapid Assessment of Avoidable Blindness survey, including the DR module.

settingA customised rural district in the catchment of Dr Shroff's Charity Eye Hospital in Uttar Pradesh in north India.

participants4095 people of age 50 years and above were enrolled using a two-staged cluster sampling, 3867 (94.4%) participated; 2167 (52.9%) were women. 3803 of 4095 (92.9%) participants were assessed for diabetes. People with already diagnosed diabetes and anyone with a random blood glucose ≥200 mg/dL were offered dilated fundus examination. PRIMARY AND SECONDARY OUTCOMES: Primary and secondary outcomes were the prevalence of DR and screening coverage for DR, respectively.

resultsThe prevalence of diabetes was 7.0% (95% CI 5.9% to 8.0%). 50.2% of all people with diabetes were newly detected. The prevalence of any DR among people with diabetes who consented to dilated pupillary examination was 22.8% (51 of 224), (95% CI 18.2% to 27.3%). 5.8% (13/224) of people with diabetes were found to have sight-threatening DR and only 15.4% (2/13) had received treatment. 84.8% of people with previously diagnosed diabetes had never had their eyes tested for DR; this was significantly higher in women (90.2% vs 76.0%, respectively, p<0.001). 76% of people with previously diagnosed diabetes had poorly controlled diabetes; this was significantly higher for those on non-allopathic treatment (p<0.01). The odds of DR were higher with duration of diabetes >10 years and poor glycaemic control (OR of 1.8 and 1.6, respectively), but this was not found to be statistically significant.

conclusionThe prevalence of DR in this predominantly rural setting was found to be higher than the national average. Coverage of retinal screening and treatment was found to be very low. Working with general health providers to increase detection of people with diabetes and leveraging vision centres to improve DR screening coverage is needed in this region.
