Effect of high-intensity exercise on functional capacity, cardiorespiratory function and quality of life in patients with colorectal cancer: a systematic review and meta-analysis.
Synthesis in Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 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
purposeColorectal cancer (CRC) accounts for a tenth of all cancers and cancer-related deaths diagnosed annually worldwide, with incidence and mortality rates significantly lower in women compared to men. High-intensity interval training exercise (HIIT) is a type of physical activity that has shown benefits in other cancer populations. The objective of this systematic review and meta-analysis is to determine the benefits in health outcomes, and the viability of this type of training on CRC patients and survivors who have undergone a HIIT intervention.
methodsA search was conducted in the Pubmed, Cochrane, Scopus and SPORTDiscus databases. Randomized clinical trials were selected. ROB 2.0 was used to analyze the risk of bias. The variables included were cardiorespiratory capacity, body composition, fatigue, symptoms of neuropathy induced and functional capacity.
resultsTen articles that met the inclusion criteria were included, resulting in a total of 1182 identified articles. One selected article had a low risk of bias. It is not clear that HIIT is better than moderate-intensity or standard care in terms of cardiorespiratory capacity. Body composition changed positively in the HIIT group, reducing fat mass and increasing fat-free mass over the moderate-intensity group. Fatigue was reduced more with HIIT, although not significantly. The meta-analysis did not show significant results due to the small sample of included studies.
conclusionsHIIT could be beneficial to improve several outcomes. However, heterogeneity in the interventions has been found, which prevents us from clearly stating that HIIT is the best exercise treatment option in these patients.
