Adjusted RRRs^* (CI95%) for the effects of several variables reported at baseline or at follow-up on asthma control (partial control or no control) at follow-up, in subjects with non remittent asthma (n = 127).

The reference category is control. *RRRs were obtained through a multinomial logistic regression model with the controlled group as the reference category. RRRs were also adjusted for the type of interview (telephone vs face to face). RRRs significantly different from 1 are reported in bold (p<0.05).
