Psychosocial factors of dietary self-management behavior based on Integrated Theory of Health Behavior Change in elderly breast cancer patients treated with chemotherapy: a multicenter cross-sectional study.

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
purposeGastrointestinal side effects during chemotherapy may interfere with daily consumption of a healthy diet. From the perspective of health behavior change, elderly breast cancer patients need to engage in dietary self-management behaviors to change the unhealthy diet caused by chemotherapy, ultimately improving their nutritional status and their quality of life. These behaviors can manifest as adverse reaction coping, dietary information acquisition, nutritional supplements and dietary replacement, and dietary habit regulation.
methodsA multicenter cross-sectional study was conducted by convenience sampling from three tertiary A-level hospitals in Shaanxi and Henan Provinces. The variables included dietary self-management behavior, treatment self-regulation, outcome expectation, self-care self-efficacy, and perceived social support. Multiple stepwise regression analysis was used.
resultsA total of 868 questionnaires were ultimately analyzed. The total score for dietary self-management behavior was 68.40 ± 11.12. Living in urban areas, cancer stage II, introjected regulation, amotivation, immediate consequence consideration, future consequence consideration, positive attitude, decision making and family support were the main factors. These 10 factors explained 48.2% of the variance.
conclusionsThe performance of dietary self-management behavior needs improvement. Nursing staff should practice precise interventions related to dietary support with respect to treatment self-regulation, outcome expectation, self-care self-efficacy and social support. Moreover, women living in rural areas with low educational levels or high cancer stages constitute the targeted intervention population for the interventions.
