Abstract

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6-19 years old; European ethnicity) using a priori set criteria. A meta-analysis (N_cases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06-1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions.

Meta‐analysis of non‐right‐handedness (NRH) frequency in individuals with language/reading impairments. The forest plot shows the results of the meta‐analysis run under a random effect (RE) model. The OR estimates are shown with the 95% confidence interval and the weights (in percentages) on the overall result of OR = 1.21, CI = 1.06–1.39 (t = 3.16, p = .01).
