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

introductionThe COVID-19 pandemic increased the prevalence of psychiatric disorders, especially in young people. The University Hospital Group Paris Psychiatry and Neurosciences (also known as the Paris Psychiatry Hospital Group, PPHG) provides psychiatric care for 2.2 million Parisians. We aimed to study the evolution of the psychiatric outpatients' characteristics in the PPHG between 2019 and 2023. MATERIALS AND

methodsWe used data from the PPHG's electronic health record database. We assessed the trend in the number of patients per year between 2019 and 2023 and the number of newly admitted outpatients. We conducted both analyses by sex, age group and clinical diagnoses.

resultsThe number of ambulatory patients treated at the PPHG remained stable between 2019 and 2023 (n = 30,000). The proportion of new patients among outpatients per year dropped (-20%). We observed a significant increase in young patients (+ 200% for those aged 15-18 and + 40% for those aged 18-25) and a decrease in patients older than 60 (-20%). These evolutions were more important for personality disorders and mood disorders than schizophrenia spectrum disorders, which could explain why the increase was more pronounced in women than men for young people.

conclusionIt is one of the most extensive studies on the evolution of psychiatric outpatient care before and after the COVID-19 pandemic. This study highlighted the lack of capacity in public psychiatry, characterised by a decline in the proportion of new patients and delays between hospital discharge or emergency unit consultation and the first consultation at a public psychiatric centre.
