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

objectiveDuring the COVID-19 pandemic, an increase in anorexia nervosa (AN), specifically childhood AN, as well as in central precocious puberty (CPP) and early-onset puberty (EOP), was reported. The aim of this study was to explore whether there was a population-level association between increases in both disorders and to discuss possible underlying causes.

methodData were retrieved from the largest health insurance institution in Germany comprising approximately 3.5 million children between 0 and 14 years for the years 2019-2023. All female cases with a diagnosis of AN/atypical AN and those with CPP/EOP according to ICD-10 were included. To investigate possible specificity of associations, we also examined associations with depressive disorders (DD) and anxiety disorders (AD).

resultsDecreasing and increasing numbers of cases with EOP, CPP, and childhood AN/atypical AN showed a similar pattern during the COVID-19 pandemic. The number of diagnosed cases of AN/atypical AN combined with either CPP (Spearman's ρ = 0.45; p = 0.02), EOP (Spearman's ρ = 0.60; p = 0.003), or combined CPP/EOP (Spearman's ρ = 0.53; p = 0.008) in this time span was highly and significantly correlated. Associations with CPP/EOP were generally stronger for AN/atypical AN than for DD (Spearman's ρ = 0.45; p = 0.02) or AD (Spearman's ρ = 0.29; p = 0.11). DISCUSSION: The highly increasing prevalence of childhood AN, EOP, and CCP may reflect pandemic-associated stress and lifestyle changes and/or their effects on reproductive functioning. Pre- and peripubertal girls seem to be especially vulnerable to these environmental stressors and might react with important physical and mental impairments.
