Validation of the Brief Version of the Cancer Behavior Inventory in Breast Cancer Portuguese Patients.
Article in Journal of clinical psychology in medical settings, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Self-efficacy is a coping resource with a positive impact on well-being, quality of life, anxiety, and depression in cancer patients, even after treatment. This study focused on the validation of the Cancer Behavior Inventory-Brief Version (CBI-B) in Portuguese patients with breast cancer. The study included 115 patients with breast cancer receiving outpatient chemotherapy in four hospitals located in Portugal. Participants (N = 115) completed the translated version of the CBI-B in Portuguese and measures of quality of life (QLQ- C30), psychological distress (HADS), and illness perceptions (IPQ-B). Confirmatory factor analysis supported the four-factor original structure of the CBI-B. The Portuguese version of the CBI-B showed good psychometric properties as shown by measures of internal consistency (Cronbach's alpha = .88), test-retest reliability (intraclass correlation coefficient = .59), convergent validity with the QLQ-C30 (r = .43, p < .001), and divergent validity with the HADS (r = -.60, p < .001) and the IPQ-B (r = -.51, p < .001). The Portuguese version of the CBI-B is a valid and reliable instrument to evaluate the self-efficacy for coping in Portuguese breast cancer patients. Future studies should validate the CBI-B in patients with other types of cancer.
