Antidepressant prescribing at the start of pre- warning period, N prescriptions per 1,000 womena | Rate of change in antidepressant use (pre-warning period), N prescriptions per 1,000 women/month (95% CI)b | Rate of change in antidepressant use (post-warning period), N prescriptions per 1,000 women/month (95% CI)c | |
---|---|---|---|
Any antidepressant | 34.17 | 0.51 (0.38, 0.64) | −1.00 (−1.58, −0.43) |
SSRI | 25.40 | 0.26 (0.15, 0.36) | −0.66 (−1.14, −0.19) |

Represents the estimated number of antidepressant prescriptions per 1,000 pregnant women in January 2004.
Represents the rate of change (slope) in antidepressant prescribing during the pre-warning period (January 1, 2002 – December 31, 2003). The positive values (with 95% confidence intervals [CIs]) are rates of increase, expressed as number of prescriptions per 1,000 pregnant women per month.
Represents the rate of change (slope) in antidepressant prescribing during the post-warning period (November 1, 2004 – July 31, 2005). The negative values (with 95% confidence intervals [CIs]) are rates of decrease, expressed as number of prescriptions per 1,000 pregnant women per month.
