Field usability and validity of eye-tracking instrumentation with the Early Childhood Vigilance Test among children aged 2-4 years old in Northern Coastal Ecuador.

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
objectiveThere is a need for effective cognitive assessment tools to evaluate the development of very young children in resource-limited low- and middle-income country settings. Our objective was to evaluate the field usability of a computer-based attention test and its concurrent validity with a caregiver-reported screener of neurodevelopment in rural, Ecuadorian children.
methodTo assess a computer-based attention test in a resource-limited setting, 41 Ecuadorian children between 2 and 4 years of age were evaluated once with the Early Childhood Vigilance Test (ECVT) of attention adapted to eye-tracking instrumentation. To evaluate the validity of the ECVT, results were compared with the Ages and Stages Questionnaire-3, measured 3-4 times between 21 and 48 months of age.
resultsECVT measures were collected successfully for 97.6% of children (40/41), suggesting good field usability of the test in this resource-limited setting. An increase in 1 SD in child attention, as measured by the ECVT average fixation duration, was associated with a 7.9-point increase in the overall Ages and Stages Questionnaire-3 score (95% CI [1.5, 14.2],
conclusionsA computer-based attention assessment in early childhood was usable in a resource-limited setting and predictive of a caregiver-reported screener of child neurodevelopment. The ECVT, therefore, can be used to assess the effects of early risk factors and resilience in brain/behavior development. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
