Study Arms:
- Citalopram (Type: EXPERIMENTAL): Citalopram was initiated at 10 mg daily for one week, with dosage increased to 20 mg daily during week 2, with an optional increase to 40 mg daily at week 4 or thereafter if response was judged to be suboptimal (CGI-I or CGI-S \> 2).
- Placebo (Type: PLACEBO_COMPARATOR): Placebo administered in capsules identical to those containing citalopram using microcrystalline cellulose.
