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

backgroundCurrently, there is no accepted system for the classification of psychotherapies for application within systematic reviews. The creation of anuncomplicated, understandable and practical classification system is neccessary for conducting reliable systematic reviews.

objectiveTo devise a system for classification of psychotherapy interventions-for use, initially, in systematic reviews.

methodsCochrane Schizophrenia's Register used as the source of randomised controlled trial. After being piloted and refined at least twice, finally we applied it to all relevant trials within the register. Basic statistical data already held within the register were extracted and used to calculate the distribution of schizophrenia research by form of psychotherapy.

findingsThe final classification system consisted of six definable broad 'boughs' two of which were further subdivided into 'branches'. The taxonomy accommodated all psychotherapy interventions described in the register. Of the initial 1645 intervention categories within the register, after careful recoding, 539 (33%) were psychotherapies (234 coded as 'Thought/Action' (cognitive & behavioural)-1495 studies; 135 'Cognitive Functioning'-652 studies; 113 'Social'-684 studies; 55 'Humanistic'-272 studies; 23 'Psychoanalytic/dynamic'-40 studies; and 63 'Other'-387 studies). For people with schizophrenia, across categories, the average size of psychotherapy trial is small (107) but there are notable and important exceptions.

conclusionWe reported a practical method for categorising psychotherapy interventions in evaluative studies with applications beyond schizophrenia. A move towards consensus on the classification and reporting of psychotherapies is needed. CLINICAL IMPLICATIONS: This classification can aid clinicians, clinical practice guideline developers, and evidence synthesis experts to recognise and compare the interventions from same or different classes.
