Complement system dysfunction in autism spectrum disorder: evidence for altered C1q and C3 levels (complement system dysfunction in ASD).
Article in Acta neuropsychiatrica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Autism spectrum disorder (ASD) is a neurodevelopmental condition characterised by impairments in social communication, repetitive behaviours, and restricted interests. Emerging evidence suggests that immune system dysregulation, particularly alterations in the complement system, may contribute to ASD pathophysiology. This study aimed to compare the serum levels of complement proteins (C1q, C2, C3, C4, MBL, L-ficolin, and hsCRP) between children with ASD and non-ASD controls. A total of 88 children (44 with ASD and 44 age- and sex-matched healthy controls) participated in this study. Complement protein levels were measured using enzyme-linked immunosorbent assay (from serum samples. The severity of ASD symptoms was assessed using standardised diagnostic tools, including the Childhood Autism Rating Scale, the Autism Behaviour Checklist, and the Repetitive Behaviour Scale-Revised. Serum C1q levels were significantly lower in the ASD group (
