Measures
Clinical and demographic variables were evaluated in all included and excluded patients. Age was evaluated by interviewing the patient or the legal guardian. Race, medical history, and hospital information were determined based on patient reports. The main outcome of this study was the reason for patient exclusion from the clinical trial. This outcome was divided by clinical (any medical information that excluded patients according to the trial protocol), technical (tDCS equipment failure), or socioeconomic reasons (difficulty with transportation, lack of caregivers to accompany them to sessions, lack of telephone contact, low interest in participating in the research, or failure to attend the scheduled evaluations).
