Effectiveness of early detection and coordinated referral of infants before 1 year at risk for autism spectrum and neurodevelopmental disorders in maternal and child protection centre: a French randomised pragmatic trial in a stepped-wedge trial (PRECO-TSA protocol).
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05815095 (Randomized Pragmatic, Cluster, Stepped-wedge Trial of Early Detection and Referral for Autism and Neurodevelopmental Disorders at the Maternal and Child Protection Services for Care Before 1 Year of Follow-up), which is not on this map. Not yet cited in PubMed.
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.

Abstract
introductionAutism and neurodevelopmental disorders (NDDs) are complex conditions that manifest as significant impairments in social communication and behaviour. Early detection and intervention play a pivotal role in improving outcomes, largely due to the high brain plasticity in infants. The PRECO-TSA study aims to validate the effectiveness of systematic use of the Prévention de l'Autisme (PREAUT) grid for early screening and referral strategies for autism and NDDs in infants, focusing on a coordinated approach that integrates maternal and child protection centre with medical-psychological centres. The goal is to evaluate a streamlined referral system to improve early detection and facilitate effective interventions for children at higher risk of autism. METHODS AND ANALYSIS: The PRECO-TSA study is a prospective, pragmatic, multicentre, cluster-randomised controlled trial using an incomplete stepped-wedge design, which maximises external validity. The study includes a 6-month baseline phase, a 3-month semiobservation phase and a 6-month follow-up phase. The 36-month patient inclusion period is followed by a 48-month passive follow-up through the National Health Data System, data collection includes demographic and clinical information, with hierarchical mixed models used to analyse the impact of early screening and referral for autism and NDDs. ETHICS AND DISSEMINATION: This study was funded by the French Ministry of Health (PREPS-20-0186) and was approved by Ile de France I Ethics Committee CPP (number CPPIDF1-2023-DI29-Cat2). The results will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT05815095.
