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
purposeAlthough targeted therapies have prolonged survival in human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer, the resulting chronic disease trajectory is frequently accompanied by substantial psychological burden. This study aimed to conduct a preliminary investigation into the feasibility and psychological outcomes of a low-intensity, group-based cognitive-behavioral therapy intervention (CBT-OP-4) among women receiving palliative care.
methodsA prospective feasibility study without a control group was undertaken involving 13 female participants (mean age = 63 years, SD = 8.05), all diagnosed with HER2-positive metastatic breast cancer. The four-session CBT-based group intervention targeted key psychological domains. Self-reported measures of distress, depression, anxiety, perceived stigma, self-compassion, and locus of control were administered pre- and post-intervention. Feasibility and acceptability were further examined via semi-structured qualitative interviews and standardized patient satisfaction instruments.
resultsFollowing the intervention, pre-post improvements were observed in psychological distress, depressive symptoms, and perceived stigma. In parallel, participants demonstrated an increase in self-compassion. Overall, the program was rated as highly acceptable, with participants emphasizing the relevance and applicability of the intervention content within their illness context.
conclusionFindings from this preliminary study suggest that the CBT-OP-4 program is a feasible and acceptable psycho-oncological intervention for women with advanced-stage HER2-positive breast cancer receiving palliative care. The results offer initial empirical support for the incorporation of structured, evidence-based psychological interventions into the routine psychosocial management of this patient population.
