Short- and long-term effectiveness of physical activity interventions for women living with and beyond breast cancer: a systematic review and meta-analysis.
Synthesis in Breast cancer (Tokyo, Japan), 2026. 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
backgroundPhysical activity is beneficial for women living with and beyond breast cancer. Many interventions aim to increase physical activity in this population; however, their effectiveness is uncertain. This review examines changes in physical activity levels across short- and long-term timepoints following these interventions.
methodsOnline databases (CINAHL Ultimate, Medline, ProQuest, PsycINFO, SCOPUS, and Web of Science) were systematically searched for studies evaluating physical activity interventions for women living with and beyond breast cancer, assessing physical activity outcomes at baseline, post-intervention (short-term), and at least 3 months from the end of the intervention (long-term). Random-effects multilevel models were used for meta-analyses.
resultsThe review included 43 studies with 5295 participants. Of these, 28 had sufficient data for meta-analyses. For between-group analyses, moderate-to-vigorous physical activity (MVPA) showed moderate effects at post-intervention (SMD = 0.46, 95% CI [0.17, 0.75]), while total physical activity showed small-to-moderate effects (SMD = 0.33, [0.15, 0.51]). At long-term follow-up (range 3 months to 5 years), effects were small for MVPA (SMD = 0.24, [0.14, 0.35]) and total physical activity (SMD = 0.25, [0.08, 0.43]). For within-group analyses, MVPA showed small-to-moderate effects (SMD = 0.38, [0.12, 0.63]) at post-intervention, while total physical activity showed moderate effects (SMD = 0.46, [0.14, 0.77]). At long-term follow-up, change from baseline MVPA was not statistically significant, while total physical activity showed a moderate effect (SMD = 0.33, [0.18, 0.47]).
conclusionsPhysical activity interventions for women with and beyond breast cancer appear effective in the short term. However, long-term effects are inconsistent, especially for intensive activity. Identifying influential factors, including psychological determinants, that promote long-term physical activity would support sustained survivorship outcomes.
