STATISTICAL ANALYSIS Descriptive statistics will be calculated for participants' demographic and lung cancer-related characteristics, as well as their function- and symptom-related PROs. Descriptive statistics will also be calculated for the data collected by the study PT regarding the frequency of specific problems (e.g. shoulder pain with REST) encountered during the initiation phase, as well as the number of calls per participant during the training phase, time per call, and reasons for these calls.
