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

Over recent decades, there has been more evidence of the connection between trauma and depression. More research is needed on the relationship between different types of trauma and their combination (cumulative trauma) with respect to the severity of depressive symptoms. The extent to which trauma and cognitive processes that manifest as polarised or 'black and white' thinking affect the severity of depression has yet to be explored.

objectiveThe objective of this research was to examine the impact of cumulative trauma and polarised thinking on the severity of depressive symptoms.

methodIn total, 172 patients, mostly women, with a diagnosis of Major Depressive Disorder or Dysthymia (or both) were evaluated using the Cumulative Trauma Scale. The Repertory Grid Technique was used to measure polarised thinking, and the Beck Depression Inventory-II was used to assess the severity of depressive symptoms.

resultsThe severity of depressive symptoms was strongly associated with a high level of polarised thinking and a high frequency of perceived negative trauma.

conclusionsOur findings underscore the need to address polarised thinking and trauma (when present) as a target of interventions aimed at reducing depression symptoms.
