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: Self Help Plus (SH+) is a WHO intervention that provides strategies for managing distress arising from adversity. In the Palestinian context, SH+ holds promise in supporting psychological well-being and mitigating the impact of trauma, with the critical challenge in adapting and scaling the intervention for feasible and sustainable delivery. Methods: This is the piloting phase of a prospective hybrid type-1 non-randomised follow-up study investigating the implementability and effectiveness of SH+ in early 2023 in the Gaza Strip. Participants were recruited by the Gaza Community Mental Health Programme, which also facilitated the intervention. Assessments were conducted immediately before and one week after the intervention. Exposure to traumatic events was measured by the Gaza Trauma Checklist (GTC). Implementability was evaluated using the Feasibility of Intervention Measure, the Acceptability of Intervention Measure, and the Intervention Appropriateness Measure. Effectiveness was assessed using the Depression, Anxiety, and Stress Scale-21 items (DASS-21), the WHO-5 Well-being Index, and the WHO Disability Assessment Schedule (WHODAS 2·0)-12 items. After each session, the facilitators completed an online fidelity test for the intervention. Findings: Of 177 eligible participants, 162 completed the pre-assessment, and 157 the post-assessment. Results indicated that 151 participants (96·16%) found SH+ acceptable, 131 (83·44%) appropriate, and 139 (88·45%) feasible. In terms of effectiveness measures, the estimated average psychological well-being score increased from 10·78 (SE = 0·42) to 17·69 (SE = 0·41), indicating a substantial enhancement in well-being. The disability scores were estimated to decrease, on average, from 22·70 (SE = 0·63) to 18·35 (SE = 0·53), and significant improvements were also observed across all DASS subscales, and in the global DASS score, with fitted model values declining from 58·97 (SE = 1·85) to 33·02 (SE = 1·71). Interpretation: The pilot phase of the study shows that SH+ is a scalable psychological intervention for individuals exposed to trauma in the Gaza Strip. Conducting the implementation phase is needed to confirm the findings. Funding: None.
