Frequency and risk factors for hydroxychloroquine retinopathy among patients with systemic lupus erythematosus.
Article in The Egyptian journal of internal medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
backgroundHydroxychloroquine (HCQ) is an antimalarial drug, recently used in COVID-19 treatment. Also it is considered over many years the cornerstone in treating systemic lupus erythematosus (SLE) in adults and children. The incidence of retinal affection and retinal toxicity from hydroxychloroquine is rare, but even after the HCQ is stopped, loss of vision may not be reversible and may continue to progress. Fundus autofluorescence (FAF) is one of the screening methods recommended by AAO used for the diagnosis of hydroxychloroquine retinopathy. Our aim is to detect early HCQ-induced retinopathy among SLE patients and the risk factors for its development by using fundus autofluorescence.
resultsIn the present study, 11.3% of the studied patients had significant visual field changes upon testing. Of those, 6.3% had abnormal fundus autofluorescence. We found a significant statistical relation between hydroxychloroquine retinopathy and the duration and cumulative dose of hydroxychloroquine therapy (
conclusionFrequency of SLE patients who had confirmed HCQ-induced retinopathy was 6.3%. Hydroxychloroquine could be safely used in all SLE patients regardless of age, sex, and SLE activity. Routine ophthalmological assessment is recommended for SLE patients who received HCQ especially for those who received HCQ longer than 7 years. Fundus autofluorescence is a modern objective tool which is specific for the early detection of HCQ retinopathy.
