Development and Validation of a Simulation Model-Based Tool to Support Individualized Physical Activity Discussions and Prescriptions for Breast Cancer Survivors.

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
purposeClinical guidelines recommend offering individualized physical activity prescriptions to cancer survivors. However, there are limited tools to support individualized physical activity discussions and prescriptions. We developed and validated a simulation model-based tool to estimate individualized survival outcomes for postdiagnosis physical activity among postmenopausal breast cancer survivors.
methodsWe adapted an established simulation modeling approach developed within the Cancer Intervention and Surveillance Modeling Network to estimate breast cancer-specific and all-cause survival associated with postdiagnosis physical activity for 50- to 75-year-old (postmenopausal) women with stage I to III invasive breast cancer. Model estimates were generated for 60,480 subgroups based on age, weight status (BMI), stage, tumor subtype, treatment, aerobic (<30 min/wk [no/minimal], ≥30 to <150 min/wk [insufficient], ≥150 to <300 min/wk [active], ≥300 min/wk [highly active]), and muscle-strengthening (<2 or ≥2 d/wk) activity. The outcomes were 10-year survival and absolute survival benefits for different levels of physical activity by individual characteristics and treatment. Model inputs were derived from trials, cohort studies, registry, and surveillance data. External validation used independent data.
resultsSurvival rates and absolute benefits for physical activity varied by age, weight status, stage, tumor subtype, and amount and type of activity. For example, the 10-year breast cancer-specific and all-cause survival for no/minimal activity in a 65- to 69-year-old-woman with stage II, hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer with obesity was 79.2% and 72.2%, respectively. Increasing aerobic activity from no/minimal to insufficient activity with <2 d/wk of muscle-strengthening was associated with absolute increases in 10-year breast cancer-specific and all-cause survival by 2.8 and 3.4 percentage points, respectively. The model closely replicated survival rates in independent data.
conclusionSimulation model-based estimates could support clinical tools for guideline-recommended individualized discussions and physical activity prescriptions for breast cancer survivors.
