Exploring Factors Related to Social Isolation Among Older Adults in the Predementia Stage Using Ecological Momentary Assessments and Actigraphy: Machine Learning Approach

To assess differences in general characteristics between the 2 groups for social interaction frequency and level of loneliness, chi-square tests and independent 2-tailed t tests were performed. The ML models were evaluated using the area under the receiver operating characteristic curve (AUC), accuracy, precision, specificity, and F1-score.

Evaluating a Mobile Digital Therapeutic for Vasomotor and Behavioral Health Symptoms Among Women in Midlife: Randomized Controlled Trial

Evaluating a Mobile Digital Therapeutic for Vasomotor and Behavioral Health Symptoms Among Women in Midlife: Randomized Controlled Trial

Significant main effects of time were followed up with 2-tailed paired t tests to aid in the interpretation of results. We also evaluated whether participants who completed all 6 weeks of treatment significantly differed from noncompleters in terms of clinical characteristics (eg, hot flush severity). We did not expect differences; however, it is important to evaluate to determine whether premature discontinuation was driven by differences in clinical severity.
