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
Background: The Brief Psychiatric Rating Scale - Expanded version (BPRS-E) is a 24-item clinician-administered scale whereby severity of psychopathology is rated using seven scoring categories for each item. Although useful in research and clinical settings, the construct validity has not been tested in South Africa. Aim: Examine the construct validity of the BPRS-E using Rasch model analysis. Setting: Community psychiatric clinics in the Sedibeng District of Gauteng province, South Africa. Methods: A retrospective record review was conducted of adult psychiatric patients in whom the BPRS-E was used in routine clinical assessment by trained psychiatric nurses and doctors. Clinical records with completed BPRS-Es were purposively sampled from three community psychiatric clinics in the Sedibeng District. Data were entered into RUMM2030 Results: Clinical records of 192 patients (93 males and 99 females; aged between 18 and 79 years) were reviewed. Total BPRS-E scores ranged from 24 to 93, with a score of 39 or less in 52% of records ( Conclusion: This study supports the construct validity of the BPRS-E items when used clinically in a South African community psychiatric setting. However, severity scoring using the BPRS-E scoring categories in this setting requires further investigation. Contribution: This study provides evidence that the BPRS-E is valid in a community psychiatric setting in South Africa.
