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

backgroundA fully dimensional model of psychosis implies that psychotic-like experiences (PLEs) connect the entire psychosis spectrum. Three types of self-reported PLEs-persecutory ideation, bizarre experiences, and perceptual abnormalities-are commonly found in the general population. This study assessed the construct, predictive, and incremental validity of self-reported PLEs in youth at clinical high risk for psychotic disorders (CHR).

methodsSelf-report data on PLEs (community assessment of psychic experiences; CAPE) were collected from 105 CHR youth (m

resultsSelf-reported PLEs were best represented by the same three factors found in the general population: persecutory ideation, bizarre experiences, and perceptual abnormalities. Cross-sectionally, PLEs-particularly persecutory ideation-correlated with interview-rated attenuated psychotic symptoms and self-reported psychosis proneness, depression, and anxiety. Longitudinally, baseline PLEs trended toward predicting 12-month change in positive attenuated psychotic symptoms (r = .29, p

conclusionsThree types of PLEs were valid in this CHR sample. Self-reported PLEs may be used not only to screen individuals for inclusion in the CHR classification, but also to characterize individuals within this population. Self-reported PLEs may help to forecast which CHR individuals will progress toward psychotic illness.
