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

STUDY

objectivesAlthough nightmares appear to be related to suicidal behaviors, the mechanisms which underpin this relationship are unknown. We sought to address this gap by examining a multiple mediation hypothesis whereby nightmares were predicted to have an indirect effect on suicidal behaviors through perceptions of defeat, entrapment, and hopelessness.

methodsData were collected from 91 participants who had experienced trauma and symptoms of posttraumatic stress disorder (PTSD). Nightmares were measured by summing the frequency and intensity ratings of relevant items on the Clinician-Administered PTSD Scale. Participants also completed questionnaire measures of suicidal behavior, hopelessness, defeat, and entrapment. Given the interrelations between insomnia, PTSD, and suicide, a measure of insomnia was included as a covariate. Furthermore, analyses were conducted with and without those participants who had comorbid depression.

resultsSuicidal behaviors were higher in those participants who experienced nightmares (62%), in comparison to those who did not (20%). Bootstrapped analyses provided support for the hypothesized multistep mediational model. Specifically, nightmares were both directly and indirectly associated with suicidal behaviors, through perceptions of defeat, entrapment, and hopelessness, independent of comorbid insomnia and depression.

conclusionsFor the first time we show that the relationship between nightmares and suicidal behaviors is partially mediated by a multistep pathway via defeat, entrapment, and hopelessness. Clinically, our work highlights the importance of monitoring and targeting nightmares and perceptions of defeat, entrapment, and hopelessness when working with clients who have experienced trauma.
