Color Vision in Schoolchildren with Low Birth Weight and Those Born Full-Term with Appropriate Weight for Gestational Age.

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 color discrimination in schoolchildren with low birth weight (LBW) and those born full-term and at a weight appropriate for gestational age (AGA).
methodsLBW children aged 5-11 years and school-, grade-, sex-, and age-matched full-term (birth weight ≥ 2500 g) AGA controls from 14 randomly selected schools from a low-income region were tested. Examinations included visual acuity, ocular motility, and color vision testing using the Farnsworth D-15 test. Color score and interocular color score difference (ICD) were compared between the groups. Multiple logistic regression was used to analyze associations between color vision deficit and group, adjusting for age, sex, visual acuity, strabismus, and amblyopia.
resultsA total of 291 LBW children (age = 8.5 ± 1.3 yrs; 55.7% females) and 265 AGA children (age = 8.5 ± 1.4 yrs; 56.2% females) were examined. Dyschromatopsia was detected in 10.3% of LBW and 7.9% of AGA children, primarily involving tritan and non-specific defects. Color scores were comparable between the groups, and color deficit was significantly associated with younger age and worse visual acuity. The ICD was statistically larger (
conclusionsMost LBW children demonstrated normal color discrimination, but their interocular color score difference was larger than that of AGA children.
