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
The prevalence of autism spectrum disorders (ASD) was studied in children in the County of Gipuzkoa (Basque Country, Spain) as part of the European Union's Autism Spectrum Disorder in Europe project (ASDEU- https://asdeu.eu ). To identify cases in a total community sample of 7- to 9-year-old pupils (N = 14,734), a multistage approach was adopted: in the first stage, a teacher nomination (TN) form was completed by school teachers; and in the second stage, all families with a child nominated by their teachers were invited to complete the Social Communication Questionnaire (SCQ). A total of 108 (59%) schools participated fully, yielding a final sample of 9177 of 14.734 (61.9%) pupils. A total of 212 (2.3%) children were nominated via the TN form, and of these, 105 (49.5%) returned the completed SCQ. Twenty-five (23.8%) cases with SCQ scores ≥ 15 were invited to undergo a free clinical assessment, and 10 (40%) new cases of ASD were identified. The prevalence estimate included the 55 cases already being supported by the Gipuzkoa's only ASD association, the Gipuzkoa Autism Society (Asociación Guipuzcoana de Autismo/GAUTENA)), as well as the 10 new subjects identified by the ASDEU field diagnostic process. A sensitivity analysis was performed to estimate new potential ASD cases among the non-participant schools, leading to a final figure of 87 cases of ASD in this age-bracket at the date of the study. This global probabilistic estimate, including non-participating schools, would thus provide a population prevalence of 0.59% (95% CI 0.48-0.73), a result lower than those reported by some other studies. Attrition rates in cross-sectional studies are challenging and support the need for developing longitudinal ASD incidence surveillance study areas (ASD observatories).
