Both Hands Assessment for children and adolescents with bilateral cerebral palsy: Content and construct validity.
Article in Developmental medicine and child neurology, 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
aimTo investigate the content and construct validity of the Both Hands Assessment (BoHA) for children and adolescents with bilateral cerebral palsy (CP), classified in Manual Ability Classification System (MACS) levels I to III, aged 18 months to 18 years.
methodIn this cross-sectional study, we included 61 adolescents with bilateral CP (37 males, 24 females, mean age 15 years 6 months, SD = 2 years 3 months) who were assessed with the BoHA to investigate content validity. Their BoHA results were combined with data from 210 children (121 males, 89 females, mean age 6 years 4 months, SD = 3 years 1 month), resulting in 271 BoHA assessments for the Rasch measurement model analyses investigating construct validity.
resultsAfter revising the bimanual item 'orients objects', the BoHA items were suitable for scoring bimanual performance in adolescents. Strong internal scale validity and reliable item and person measures were demonstrated for the 16 BoHA items, analysed separately for individuals with asymmetric (n = 94) and symmetric (n = 177) hand use. The BoHA logit measures were linked to the same reference frame, enabling comparable overall bimanual performance measures while maintaining separate item difficulty hierarchies.
interpretationThe BoHA scale can measure bimanual performance in individuals with bilateral CP, classified in MACS levels I to III, aged 18 months to 18 years. This allows for monitoring development and evaluating the effectiveness of intervention from early childhood to adulthood.
