Dear Dr. Hao,

I've been viewing your paper "Pregnancy loss and anxiety and depression during subsequent pregnancies: data from the C-ABC study."

There is evidence in other quarters that women with a history of both induced abortion and miscarriage are significantly more likely to experience subsequent mental health problems than women with just one of these experiences. I see that in your study, 461 women had a history of both miscarriage and induced abortion. In a broader context, there is also evidence that women with multiple losses (miscarriage or abortion) are also at higher risk. (See Increased risk for postpartum psychiatric disorders among women with past pregnancy loss. Giannandrea SA, Cerulli C, Anson E, Chaudron LH. J Womens Health (Larchmt). 2013 Sep;22(9):760-8.)

I am writing to request that you re-analyze tables 3 & 4 to compare (1) women with a history of at least one miscarriage and at least one abortion, and (2) women with 2, 3, or 4 or more losses (miscarriage or induced abortion) with your reference group of women with no history of pregnancy loss.

Thank you for your consideration.
