The role of prehabilitation in improving brain health and cognition after chemotherapy in patients with colorectal cancer: Study protocol of the Chemo Brain Prehab Project.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07341217 (Chemo Brain Prehab Project), which is not on this 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.

Abstract
introductionRegional disparities in the incidence of colorectal cancer remain a concern within the United Kingdom, particularly in the North West of England, with 37% higher incidences than the national average. Given the growing burden of treatment-related side effects such as cognitive impairment, this study aims to investigate whether prehabilitation can improve brain health and cognitive function in patients with colorectal cancer receiving adjuvant and neoadjuvant chemotherapy.
methodsThis randomised control trial will recruit eighty-six patients with stage II and III colorectal cancer, who will receive adjuvant and neoadjuvant chemotherapy (fluorouracil, capecitabine, or oxaliplatin) and will be randomised between prehabilitation and standard care groups. The prehabilitation group will be provided an individualised, home-based exercise programme before and during chemotherapy, multivitamin supplementation, telephone check-ins, and activity devices. The standard care group will be provided with information about physical activity and nutrition at the start of the intervention. Habitual physical activity will be tracked in all patients. Assessments will be conducted at baseline, 72 hours before the first chemotherapy administration, and 72-96 hours after the final treatment. Outcome measures will include cardiopulmonary fitness, neurotrophic biomarkers, electroencephalographic activity, cognitive function tests, and a cognitive-related quality of life assessment. DISCUSSION: This study protocol is designed to test whether home-based prehabilitation can improve brain health and reduce chemotherapy-related cognitive impairments in patients with colorectal cancer. Insights from this work may support the development of more accessible and effective prehabilitation programmes to address treatment specific cognitive impairment.
