Motivation to Participate in a Nutrition and Physical Activity Intervention During Chemotherapy for Breast Cancer: A Qualitative Study.
Trial report in Psycho-oncology, 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
objectiveTo explore the motivations for participating in a combined nutrition and exercise intervention starting during chemotherapy for breast cancer.
methodsThe Lifestyle, Exercise, and Nutrition early after Diagnosis (LEANer) trial randomized 173 women newly diagnosed with stage I-III breast cancer to a yearlong nutrition and exercise intervention (N = 87) or usual care (N = 86) during chemotherapy to assess the effect on chemotherapy adherence. Upon completion of the trial, using a stratified purposeful sampling method, a subset of women randomized to the intervention arm completed a one-time, individual, semi-structured interview. Interviews were transcribed verbatim and analyzed using thematic analysis.
resultsAmong the 29 interviews, we identified four key themes related to women's motivations for participating in a lifestyle intervention during chemotherapy. These included (1) Proactivity - a pursuit of opportunities to improve and prioritize health; (2) Altruism - a desire to help others with breast cancer and advance the science around lifestyle factors and treatment outcomes; (3) Lack of perceived harm - the benefits outweighed risks; and (4) Oncologist recommendation - an endorsement from their clinical provider played a critical role.
conclusionsWomen with breast cancer were motivated to participate in a nutrition and exercise intervention initiated during chemotherapy because of factors relating to optimizing their own health, altruistic desires, perceived lack of harm, and their oncologist's recommendation. Compared to post-treatment, the opportunity to be proactive and having an oncologist recommendation emerged as unique motivators. Understanding these drivers of motivation can enhance recruitment and promote engagement and adherence in future interventions during active cancer treatment.
