The impact of narrative exposure therapy on dysthymia and post-traumatic stress symptoms in nurses in the post COVID-19 period: a randomized clinical trial study.
Article in BMC nursing, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
objectiveThe COVID-19 pandemic imposed profound psychological strain on frontline nurses. This randomized clinical trial aimed to evaluate the effects of Narrative Exposure Therapy (NET) on dysthymia and post-traumatic stress symptoms among nursing professionals in the post-pandemic period. MATERIALS AND
methodsIn this randomized controlled trial, 60 eligible nurses from two hospitals in Isfahan, Iran, were randomly, assigned to intervention and control groups. The intervention group engaged in six weekly sessions of group NET, each lasting 90 min. The control group received treatment as usual and no active intervention. Data were collected using the Millon Clinical Multiaxial Inventory-III (MCMI-III) at baseline, post-intervention, and a one-month follow-up. Data analysis involved both descriptive and inferential statistical procedures using SPSS Version 21.
resultBaseline scores for dysthymia and post-traumatic stress symptoms were comparable between groups. The intervention group showed statistically significant reductions in symptom scores at post-intervention and one-month follow-up compared to baseline (p < 0.001). A significant time × group interaction was confirmed for both post-traumatic stress symptoms (p < 0.001, η²=0.441) and dysthymia (p = 0.02, η²=0.65), indicating substantially greater improvement in the NET group relative to the control group. No significant differences were observed between post-intervention and follow-up scores within the intervention group.
conclusionNET effectively reduces dysthymia and post-traumatic stress symptoms in nurses. While these findings suggest that NET promotes mental health recovery, the short follow-up period limits conclusions regarding long-term durability. Future longitudinal research and more diverse sampling are warranted to establish the sustained efficacy of this intervention.
