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

backgroundCognitive behavioural therapy for psychosis (CBTp) is currently a recommended form of psychosocial treatment for persons suffering from persistent psychotic symptoms. It has been argued that effect sizes from efficacy studies cannot be generalized to real clinical settings.

aimsOur aim was to evaluate whether the positive results from randomized controlled trials conducted by experts could be replicated in clinical setting with a heterogeneous sample of patients with psychotic disorder.

methodPatients referred to the study were either randomized to CBTp+TAU (the treatment group) or to a waiting-list group, only receiving TAU. The patients were assessed on different outcome measures such as the Brief Psychiatric Rating Scale (BPRS), the Scale for the Assessment of Negative Symptoms (SANS), and the Psychotic Symptom Rating Scales (PSYRATS), at pretreatment, at posttreatment (6 months), and at 12 months follow-up. In total, 45 patients participated in the study.

resultsThe results showed that 20 sessions of CBTp performed significantly better than the waiting list controls with respect to the global score on the BPRS, the delusional scale on the PSYRATS, and the GAF symptom score at posttreatment. At 12 months follow-up only the GAF symptom score remained significantly changed for the total sample.

conclusionsThe study revealed that CBTp delivered by non-experts in routine clinical settings can produce improvements in positive psychotic symptoms, and also that some of these improvements can be maintained at one year follow-up.
