Quality of Life and Metabolomics Analysis in Response to Meal Kit Intervention During Perioperative Chemotherapy in Patients with Early-Stage Breast Cancer: Protocol for a Single-Center Phase Ⅱ Randomized Crossover Trial.
Article in JMIR research protocols, 2025. 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
Background: Patients with breast cancer undergoing chemotherapy experience significant adverse effects, including fatigue, nausea, and taste alterations, leading to malnutrition in 40% of patients. Traditional nutritional counseling has shown limited effectiveness in addressing these challenges during treatment. Objective: This study aimed to evaluate the impact of a structured meal kit intervention on quality of life and metabolomic profiles in patients with breast cancer during perioperative anthracycline and taxane-based chemotherapy. Methods: This single-center phase 2 randomized crossover trial will enroll 20 patients with breast cancer scheduled for perioperative chemotherapy at Jikei University Hospital between October 2024 and October 2025. Patients will be randomized 1:1 to receive a meal kit intervention either during the first or second 3-month period of chemotherapy. The intervention consists of weekly deliveries of preportioned ingredients with dietitian-designed recipes (one 2-serving meal kit during chemotherapy weeks, two during nonchemotherapy weeks). The primary endpoint is the change in the EORTC QLQ-C30 (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30) "appetite loss" domain score. Secondary endpoints include changes in total EORTC QLQ-C30 score, plasma metabolome profiles, body composition, nutritional status, and chemotherapy completion rate. Data will be collected at baseline, crossover (12 wk), and study completion (24 wk). Results: The study was funded in March 2024. Data collection began on March 26, 2025, and as of manuscript submission, 11 participants have been recruited out of the planned 20 participants. Data analysis has not yet commenced, and results are expected to be published in Spring 2026. Conclusions: This trial will provide evidence for the effectiveness of a meal kit intervention in supporting patients with breast cancer during chemotherapy. The findings may help establish evidence-based standards for nutritional support in oncology care.
