Fig. 2: Forest plots for domain-specific meta-analyses of syntactic production and comprehension in schizophrenia.
From: Relationship between grammar and schizophrenia: a systematic review and meta-analysis
a Forest plots for Bayesian Model-Averaged estimates of group differences in syntactic comprehension (n = 16 studies). b Error detection (n = 6). c Production length (n = 17). d Phrasal complexity (n = 16). e Production integrity (n = 11). f Global complexity (n = 13). Estimated Cohen’s d values (with 95% credible intervals) reflect patient-control differences. FTD Formal Thought Disorder, nFTD no-FTD, FEP First Episode Psychosis, SCZ Established schizophrenia. Circles represent the effect of individual studies, with their size weighted by sample size; diamond lozenges represent pooled effects.
