Randomised phase-2 screening trial of intermittent energy restriction plus resistance exercise versus resistance exercise alone during chemotherapy for advanced breast cancer.
Trial report in British journal of cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundWeight control and energy restriction could improve survival in patients with advanced breast cancer (ABC) but randomised data are lacking. A randomised screening trial was conducted to assess an intermittent energy restricted diet and resistance exercise intervention (IER + RE) vs RE alone (RE) on progression free survival (PFS), toxicity and Quality of Life (QoL) during chemotherapy for ABC.
methodsSixty-eight women were randomised to IER + RE (n = 35) or RE (n = 33) with one-sided significance assessed at the 20% threshold. The primary end point was PFS secondary endpoints included chemotherapy toxicity, weight change and QoL.
resultsThe adjusted hazard rate for progression comparing IER + RE vs RE was 0.729 (0.391-1.361) and the median PFS 42.0 vs 26.1 weeks respectively (p = 0.160). Toxicity was low and comparable between groups. Comparing IER + RE vs RE alone at cycle 3 the median (interquartile range) changes were: weight -1.8 kg (-4.2 to -0.7) vs +0.2 kg (-0.74, 2.59) (p < 0.001), FACT-B + 4.0 (-0.8, 11) vs +1.0 (-4.0, 4.0) (p = 0.031) and Hospital Anxiety Depression Score -2.0 (-3.5, +0.5) vs +1.0 (-2, 3.5) (p = 0.022).
conclusionIER + RE improved PFS and QoL without evidence of harms warranting a further larger randomised study in ABC.
