Which came first, delusions or hallucinations? An exploration of clinical differences among patients with first-episode psychosis based on patterns of emergence of positive symptoms.
Article in Psychiatry research, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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.
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
Remarkably little is known about patterns of emergence of specific symptoms in the early course of nonaffective psychotic disorders. Some 159 well-characterized first-episode psychosis patients were categorized into those with: (1) delusions only (n=29, 18.2%); (2) delusions that emerged at least 1 month before hallucinations (n=31, 19.5%); (3) hallucinations that began at least 1 month before delusions (n=26, 16.4%); and (4) delusions and hallucinations that emerged concomitantly, within the same month (n=73, 45.9%). These four groups were compared across a number of clinical features, including duration of untreated psychosis, symptom severity, insight, and functioning, while controlling for potential confounders. Patients with delusions and hallucinations emerging within the same month had a shorter duration of untreated psychosis than those in whom one psychotic symptom emerged greater than one month before the other. The delusions-only group had significantly less severe positive, negative, and general psychopathology symptom scores, as well as better social and occupational functioning. Replication and further elucidation of specific patterns of symptom emergence would deepen the field's understanding of early-course phenomenology, and may inform efforts to improve upon nosology, prognostication, and treatment selection.
