*Total N for each questionnaire presented herein does not exactly coincide with Figure 1 because patients/deaths were excluded for the purposes of Landmark survival analyses for each successive exposure assessment and because 2 patients who completed Q3 did not complete Q2, and 5 patients who completed Q4 did not complete all prior questionnaires. RPA = recreational physical activity; Q = questionnaire.
