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
backgroundThere are high rates of co-occurring post-traumatic stress disorder (PTSD) among patients in treatment for substance use disorder (SUD). PTSD and SUD should be treated simultaneously, which is rarely the case. The reluctance to offer trauma-focused treatment is partially due to fear of increased risk of dropout. PTSD is related to emotion dysregulation and elevated psychological burden, higher dropout rates and increased risk of relapse. In this project, we plan to assess if it is relevant, feasible, acceptable and safe to add a combination of narrative exposure therapy (NET) and dialectical behaviour therapy for substance use disorder skills training (DBT-SUD Skills) to standard inpatient SUD treatment.
methodsWe will recruit patients from a long-term inpatient SUD treatment centre on the west coast of Norway (N approx. = 90). We will assess relevance based on the prevalence of PTSD/Subthreshold-PTSD and traumatic experiences, suicidal behaviour, self-harm, and the severity of difficulties in emotion regulation. We will assess acceptability with treatment participation among patients and the subjective experience of the treatment. We will measure safety with the rate of dropout and destructive behaviour in the treatment period. DISCUSSION: It is important to develop and evaluate treatment options for this vulnerable patient population, often excluded from clinical research. Strengths include a naturalistic setting and historical data for comparison. Limitations are the absence of a control group and inability to isolate component effects. The results can be used to develop a treatment protocol for combining NET and DBT-skills training to in patient SUD treatment for further development and testing in a multicentre Protocol following SPIRIT 2025 guidelines.
