Article in Clinical ophthalmology (Auckland, N.Z.), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04297969 (Detection of Hyperopia by Photoscreener GoCheckKids With Glow Fixation Device), which is not on this map. Cited by 7 papers, 1 of them a synthesis that pooled it.

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.

Abstract

backgroundA low-detail, glowing fixation device was added to GoCheck Kids (GCK) photoscreener in the hope of unmasking hyperopia and amblyopia risk factors (ARF).

methodsPediatric eye patients were screened by GCK and 2WIN photoscreeners, and Retinomax autorefractor before being compared to AAPOS ARFs.

resultsScreening was attempted by 131 children who then had school bus accommodation-relaxing skiascopy (SBA-RS) before cycloplegic examination. By 2013 AAPOS uniform guidelines, sensitivity/specificity for GCK was 87%/68%, for 2WIN 87%/71% and for Retinomax 79%/68%. Detection of amblyopia had sensitivity/specificity by GCK of 78%/63%, for 2WIN 79%/65% and for Retinomax 77%/68%. Inconclusive screens were seven for GCK, six for 2WIN and 13 for Retinomax. Mean hyperopia for GCK (+2.49±0.74 D) was similar to cycloplegic refraction (+2.93±0.72 D) and SBA-RS (+2.80±0.82 D) while GCK was slightly more than Retinomax (+1.59±0.93 D,

conclusionGCK, 2WIN and Retinomax had similar validity detecting uniform amblyopia risk factors and amblyopia itself. The nondetailed glow fixation device allowed GCK to uncover substantial hyperopia while the detailed flashing fixation devices on 2WIN and Retinomax seemed to stimulate accommodation in some hyperopic children. CLINICAL TRIALS REGISTRY: NCT04297969. Data Access: http://www.abcd-vision.org/references/GCK%20glow%202WIN%20deidentify.pdf. PRÉCIS: A glow fixation device on a smart phone photoscreener allowed robust detection of hyperopia.
