Hospitalizations in adolescents with autism spectrum disorder are rising in Spain.

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
backgroundAutism spectrum disorder (ASD) is a leading mental condition among adolescents globally and is associated with premature mortality. The analysis of hospitalization rates and trends in youth with ASD could be important for guiding earlier diagnosis and prompt interventions.
methodsWe retrospectively analyzed all hospitalizations in children and adolescents aged 11-18 years with ASD in Spain. The Spanish National Registry of Hospital Discharges was examined, spanning 2000 to 2021.
resultsDuring the 22-year study period, there were 2,015,589 hospitalizations among adolescents in Spain, of which 118,609 (5.9%) involved mental disorders. ASD was reported in 6,659 admissions, representing 5.6% of hospitalizations among youth with mental health disorders. Boys comprise 74.4%. Median age was 14 years old. Admissions with ASD experienced a 74-fold increase during the study period (p < 0.001). The in-hospital mortality rate for youth with ASD was 0.33%. Adolescents with ASD, as compared to those with other psychiatric conditions, had a higher rate of comorbid mental health disorders. However, intellectual disability was more frequent in youth with ASD than in the rest. Admissions of adolescents with ASD slightly declined during the first year of the COVID-19 pandemic but resumed their rising trend thereafter.
conclusionHospitalizations in adolescents with ASD have significantly increased in Spain during the last two decades. Boys represent nearly three-quarters of admissions.
