The Cognitive Status Scale: A Preliminary Investigation of Psychometric Properties in a Clinically Referred Pediatric Critical Care Sample.
Article in Neurocritical care, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCognitive morbidities persist after pediatric critical care. However, a significant gap exists related to measuring cognitive outcomes in this patient population due to heterogeneity in presentations and objective measures. This study's purpose was to develop a psychometrically sound coding system to summarize clinically generated and performance-based neuropsychological outcomes to be used for research.
methodsThe work was conducted in two stages: (1) Cognitive Status Scale (CSS) development and (2) a retrospective pilot test in a clinically referred sample of post-critical-care youth aged 6-19 years (N = 110) to explore preliminary psychometric properties of the CSS.
resultsPrincipal components analysis supported the CSS structure (capturing 59% of the total explained variance). Internal consistency (α = 0.82) and interrater reliability (r = 0.92) were good. Within the full sample, criterion-related validity was demonstrated as the CSS total composite score from long-term evaluation and was significantly correlated with abbreviated performance-based cognitive outcomes from the acute recovery phase (Neurocognitive Index, r = 0.74). Divergent validity was shown via significant differences on the CSS total composite score between known clinical groups (≥ 3 Functional Status Scale [FFS] change = 30.23 vs. ≤ 2 FFS change = 50.94, t = 4.10, p ≤ 0.001, d = 0.91) and across CSS clinical indicators (F
conclusionsPrimary evidence shows the CSS to be a reliable and valid measure for summarizing a clinically administered battery of cognitive assessments. Easy-to-generate metrics of performance-based cognition are essential to progress the state of the science germane to cognitive outcomes post pediatric critical care.
