SCFA concentrations and dietary fiber intake at baseline and 6-months post-baseline (p.-b.) in children with ASD (ASD) and unaffected controls (CONT). Concentration of all SCFAs decreased in children with ASD whereas SCFA concentrations in CONT remained stable. (A) LSCFA and (B) BSCFA concentrations at baseline and 6-months post-baseline for ASD and CONT; (C) Dietary fiber intake at baseline and 6-months post-baseline for ASD and CONT; LSCFA, linear short chain fatty acids (acetate, propionate, butyrate); BSCFA, branched short chain fatty acids (Isobutyrate, isovalerate, valerate); p.b. - post-baseline; data expressed as median (IQR); ^*p ≤ 0.05; ^†p ≤ 0.1.
