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

backgroundThere is considerable evidence that incidence of schizophrenia and other psychoses varies across ethnic groups in the UK, with particularly high rates for people of African-Caribbean origin.

aimsThe aims of this shady were to estimate in a community-based sample of people from ethnic minorities: 1) the prevalence of psychotic symptoms; and 2) risk factors for reporting psychotic symptoms.

methodFace-to-face interviews were carried out with a probabilistic sample of 4281 adults from six ethnic groups living in the UK. Psychotic symptoms were measured using the psychosis screening questionnaire (PSQ).

resultsThere was a twofold higher rate of reporting psychotic symptoms on the PSQ in Black Caribbean people compared with Whites. Adjustment for demographic factors had little effect on this association.

conclusionPrevalence rates of psychotic symptoms were higher in people from ethnic minorities, but were not consistent with the much higher first contact rates for psychotic disorder reported previously, particularly in Black Caribbeans.
