1 · What the graph read from it

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.

2 · The registry

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

The cerebellum contributes to the control of movement, language, and sociability. Purkinje cells, the main output neurons of the cerebellar cortex, are reduced in cerebellar malformations (CMs) and in autism spectrum disorder (ASD). Thus, CMs may increase the risk for ASD. We conducted a meta-analysis to determine the prevalence of ASD in individuals with CMs. We searched PubMed, Embase, and APA PsycINFO for studies assessing ASD in patients with radiologically confirmed CMs. We evaluated risk of bias using Joanna Briggs Institute Checklists. Finally, we extracted data to calculate ASD prevalence and assess variation across CM subtypes. From 1,564 screened articles, 32 studies met inclusion criteria, encompassing 1,032 individuals with CMs. ASD prevalence was 31.2%, significantly higher than the general population rate (1 in 31). High heterogeneity was observed (I² = 72.3%; p < 0.0001). Vermis and cerebellar hypoplasia reliably contributed to the high ASD prevalence. Many studies had small sample sizes and used different metrics to diagnose autism. ASD is more common in individuals with CMs, especially vermis malformations, than in the general population. Early neurodevelopmental monitoring may benefit those with prenatally diagnosed CMs.
