The Accuracy of Digital Imaging in Diagnosis of Retinopathy of Prematurity in Iran: A Pilot Study.
Article in Journal of ophthalmic & vision research. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeTo evaluate sensitivity and specificity of digital retinal image reading in the diagnosis of referral-warranted retinopathy of prematurity (ROP).
methodsInfants referred to the ROP clinic underwent fundus examination through indirect ophthalmoscopy. Fundus photographs were acquired using RetCam (shuttle 2; Clarity medical systems, Pleasanton, CA, USA). Four retinal specialists who were blind to patients' information reviewed the RetCam fundus photographs. By comparing the results of photographs' readings with that of indirect ophthalmoscopy as the gold standard, the sensitivity and specificity of telescreening was determined.
resultsA total of 147 treatment-naïve patients met the inclusion criteria and were enrolled in the study. Mean gestational age (GA) was 28.6 ± 2.0 weeks. Digital retinal imaging had sensitivity of 85% and specificity of 35% in detecting referral-warranted ROP in our study. Positive predictive value of digital photography was 80%, and negative predictive value was 43%.
conclusionDigital photography for diagnosis of ROP may show good potential as a screening modality in developing countries. It can facilitate early diagnosis, prevent unnecessary referrals, and be implemented for investigational purpose. However, the overall study result did not provide evidence to propose digital photography as a substitute for indirect ophthalmoscopy in the diagnosis of ROP.
