  1. OR Unstandardized Odds Ratio, 95%-CI 95% Confidence Interval of OR, ORstandardized Standardized (z-scaled) OR, z z-Value, p p-value. Participation was measured as the number of future waves in which the baseline population was participating (0 to 3). The participation count refers to the number of future waves the participants participated in
