Regression results predicting Time 2 PEFR values (L/min) from total social roles
at Time 1, adjusting for individual differences in Time 1 PEFR, age, gender,
ethnicity, education, height, and weight (N = 4028).
The total number of social roles variable was centered around a mean of 0. The
total number of social roles at Time 1 was positively and linearly associated
with PEFR at Time 2, β = 0.050,
b = 5.144, p < .001,
CI95 = [3.187, 7.101].
