Examining the psychometric properties of the WISC-IV in low and normal IQ samples.
Article in BMC psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) is one of the leading instruments in general ability assessments; however, findings regarding its factor structure are still controversial.
methodsIn this study, the single-factor, correlated four-factor, higher-order factor, and bifactor models for the 10 basic tests of the WISC-IV were examined on systematically controlled samples with low (IQ ≤ 79; N = 141) and normal scores (IQ > 80; N = 222).
resultsOur research findings revealed that only the bifactor and correlated four-factor models showed good fit in both sample groups; however, measurement invariance was provided only by the correlated four-factor model.
conclusionsIn general, our findings indicate that the use of the full-scale intelligence quotient (FSIQ) score should be used with caution in both low and normal IQ groups and that it would be more appropriate to prefer subscale index scores, especially in educational and clinical assessments.
