Main outcomes: outcome rates, unadjusted odds ratios (OR) with 95% confidence intervals, and odds ratios after multiple logistic regression analysis, adjusting for gender, age, chief complaint, duration of complaint, complaint episode within last 12 months, baseline symptom score, and concomitant disease present at baseline. Odds ratio >1 indicates better outcome in A-group. *at all available follow-ups.
