Evaluating a Portable, Noncontact Fundus Camera for Retinopathy of Prematurity Screening by Nonophthalmologist Health Care Workers.
Article in Ophthalmology. Retina, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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 (1) the feasibility of non-ophthalmologist healthcare workers (HCWs) to obtain images of sufficient quality for retinopathy of prematurity (ROP) screening using a FDA-approved portable, non-contact, narrow-field fundus camera (i.e., Pictor™), and (2) the accuracy of grading these images to identify infants who developed treatment-warranted (type 1) ROP.
designProspective cohort study. SUBJECTS: Infants undergoing routine ROP screening examinations (i.e. birth weight ≤1500 grams and/or gestational age ≤30 weeks or selected infants with a birth weight of 1500-2000g or gestational age >30 weeks and an unstable clinical course).
methodsWe prospectively recruited infants undergoing ROP screening examinations at a community hospital. On the same day an ophthalmologist examined them, a trained HCW imaged their retinas using the non-contact camera. Two masked ROP experts graded these images remotely. We calculated both the percentage of gradable images (i.e. having at least 3 quadrants with sufficient image quality), as well as the accuracy of identifying infants who developed type 1 ROP.
main outcome measuresPercentage of gradable images and the sensitivity and specificity of each grader for identifying infants with type 1 ROP by grading for the presence of pre-plus or plus disease.
resultsNinety-nine infants were included. Overall, 92.4% and 94.2% of all infant imaging sessions were considered gradable by graders 1 and 2, respectively. Amongst gradable images, the sensitivity of both graders for identifying type 1 ROP by grading for the presence of pre-plus or plus disease was 100% (95% confidence interval (CI): 95-100%) and the specificity 91% (95% CI: 83-95%) for grader 1 and 93% (95% CI: 86-96%) for grader 2.
conclusionsIt was highly feasible for trained HCWs to obtain digital retinal images of sufficient quality for ROP screening using a non-contact fundus camera. By grading for the presence of pre-plus or plus disease, graders identified infants who developed type 1 ROP with high sensitivity and specificity. The use of portable, non-contact retinal cameras by trained HCWs could increase our workforce in ROP screening and identify infants needing an indirect ophthalmoscopy examination by an ophthalmologist.
