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

Research has sought to understand insomnia through identification of subtypes, yet age of onset has received limited focused empirical attention. This investigation aimed to detect clinically distinct age of insomnia onset subgroups utilising latent profile analysis (LPA). Participants were 618 adults, aged 18-71 years (M = 28.94, SD = 11.06), with insomnia. Participants completed a survey assessing insomnia natural history and causal attributions; sleep disturbance and impairment; pre-sleep arousal and threat monitoring; stress, mental and physical health; and social functioning. LPA was performed on age of insomnia onset. Binary logistic regression analyses were performed to evaluate associations between clinical measures and early versus late onset insomnia with statistical adjustment for chronological age and sex. Results showed a two-class model (Class 1: n = 547, 88.5%, M
