Table 2 Regression summaries for multivariate analysis with the dependent variable % change in VO2max from before treatment to six months follow up. The coefficients are given with 95% confidence intervals

From: The Phys-Can observational study: adjuvant chemotherapy is associated with a reduction whereas physical activity level before start of treatment is associated with maintenance of maximal oxygen uptake in patients with cancer
