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
backgroundThe ability to derive growth from a traumatic event, such as a cancer diagnosis, can facilitate effective adaptation to the challenges associated with cancer survivorship.
objectiveIn two studies, we investigated the possible cognitive mechanisms explaining the relationship between post-traumatic stress and post-traumatic growth in female survivors of breast cancer. Specifically, Study 1 examined the role of interpretation bias, and Study 2 examined the role of cognitive restructuring of trauma.
methodsIn Study 1, 113 participants completed questionnaires assessing stress- and anxiety-related symptomatology, post-traumatic stress and growth, perceived cognitive functioning, and positive interpretation bias. In Study 2, 117 participants completed questionnaires assessing stress and anxiety-related symptoms, rumination, perceived cognitive functioning, cognitive restructuring of trauma, and post-traumatic stress and growth.
resultsIn both studies, post-traumatic stress was negatively related to post-traumatic growth. In Study 1, positive interpretation bias explained a significant amount of variance in the relationship between post-traumatic stress and post-traumatic growth, with perceived cognitive functioning moderating the relationship between interpretation bias and post-traumatic growth. In Study 2, cognitive restructuring explained a significant amount of variance in the relationship between post-traumatic stress and post-traumatic growth, with deliberate rumination moderating the effects of cognitive restructuring on post-traumatic growth.
conclusionsCognitive mechanisms are key to understanding the relationship between post-traumatic stress and growth and should be targeted in interventions to improve cognitive flexibility and resilience among breast cancer survivors.
