Sensitivity and specificity of pseudocolor ultrawide field imaging in comparison to wide field fundus fluorescein angiography in detecting retinal neovascularization in diabetic retinopathy.
Observational study in Eye (London, England), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectiveTo evaluate the diagnostic accuracy of ultrawide pseudocolor retinal photography (pseudocolor UWF) compared to wide field fundus fluorescein angiography (WFFFA) in the detection of retinal neovascularization (NV) and NV of the disc (NVD) in patients with diabetic retinopathy (DR).
designDiagnostic accuracy observational study evaluating pseudocolor UWF as the index test. The reference standard was WFFFA.
settingSingle retinal centre in India.
participantsPeople with severe non-proliferative DR (sNPDR), early proliferative DR (ePDR) or high-risk proliferative DR (HR PDR).
main outcome measuresSensitivity and specificity of pseudocolor UWF in the detection of NV.
resultsA total of 176 eyes of 94 subjects with sNPDR, ePDR or HR PDR underwent pseudocolor UWF and WFFFA. The sensitivity and specificity of pseudocolor UWF in detecting NVE were 92.5% (95% CI 86.2-96.5) and 81% (95% CI 64.8-92.0), respectively, with moderate interobserver agreement of 0.722 (p value 0.001). The positive predictive value and negative predictive value were 83.0 (71.4-90.5) and 91.5 (84.9-95.3), respectively.
conclusionCompared to WFFFA as the gold standard, pseudocolor UWF has high sensitivity and specificity in detection of NV in all retinal quadrants and NVD. Therefore, pseudocolor UWF may be used as a non-invasive tool for screening and managing DR.
