Contrast Sensitivity and Low-Contrast Visual Acuity in Children With Low Vision.

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
Purpose: To investigate distance and near contrast sensitivity (CS), as well as low-contrast visual acuities (LCVAs) at 5% and 2.5% contrasts across various eye diseases causing low vision, in children aged 5 to <16 years, and to study the repeatability of these measures. Methods: In total, 782 children (age, mean ± SD, 10.23 ± 2.75 years) with low vision, visual acuity between 0.3 and 1.3 logMAR, or visual field with mean deviation worse than 12 dB were recruited. CS was assessed with Pelli-Robson distance and near tests. Visual acuity and LCVAs at 5% and 2.5% contrast were assessed using LEA symbols. In 134 children, data were collected again in approximately 3 months for repeatability measures. Bland-Altman 95% limits of agreement (LoAs) were used to assess repeatability. Results: A wide range of CS (distance: 1.69 to 0.45 logCS, near 1.73 to 0.15 logCS) and LCVA (0.80 to 1.54 logMAR at 5% contrast and 0.94 to 1.58 logMAR at 2.5% contrast) were observed across 47 eye diseases in children with low vision. Repeated measures for CS and LCVA exhibited a large variation (LoA: distance CS = 0.44 logCS, near CS = 0.54 logCS, LCVA 5% = 0.38 logMAR, LCVA 2.5% = 0.42 logMAR) in children with low vision. Conclusions: CS and LCVA impairments vary across eye diseases in children. A difference of more than 0.45 logCS (three triplets) in CS or 0.4 logMAR (four lines) in LCVA during follow-up is considered clinically meaningful for children with low vision due to high test-retest variability.
