Table 5 Stepwise linear regression model estimating predictors of the frequency of meeting the “Combined” or “Neither” guideline during follow-up (n = 245)

From: Patterns and predictors of exercise behavior during 24 months of follow-up after a supervised exercise program during breast cancer chemotherapy
