Revisiting insulin resistance in human cancer cachexia - a systematic review and meta-analysis.
Synthesis in Acta oncologica (Stockholm, Sweden), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundIn patients with cancer, unintentional weight loss and cancer-associated cachexia (CAC) reduce overall survival and impair the quality of life. Because of insulin's anabolic effects, insulin resistance could contribute to CAC progression. However, the role of insulin resistance in CAC remains unclear, and this study aimed to investigate the association between insulin resistance and CAC. Addressing this knowledge gap may help identify treatable targets to improve patient outcomes.
methodsWe performed a systematic review and meta-analysis. By including studies reporting both fasting levels of circulating insulin and glucose in patients with cancer and CAC according to the internationally accepted CAC definition, we calculated the HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) index to estimate the level of insulin resistance (defined as HOMA-IR above 2.0) in patients with CAC. A subgroup analysis was conducted from studies reporting a HOMA-IR index both from a group of patients with CAC and a group without CAC (nonCAC).
resultsSeventeen studies were included, with a total of 197 patients. The mean HOMA-IR of all studies was 1.84 (95% confidence interval [CI]: 1.77-1.91). Twelve studies found HOMA-IR below 2.0. Five of the 17 studies also reported HOMA-IR from a group of patients with cancer without CAC. We observed a mean difference of -0.42 (95% CI: -2.24 to 1.40) in favour of a lower HOMA-IR in patients with CAC compared to nonCAC, and thus no statistically significant difference between the groups.
interpretationThis systematic review suggests no clear association between insulin resistance and CAC. However, the limited sample sizes and study heterogeneity highlight the need for larger, longitudinal investigations.
