NOTES: This table shows the total sample of married female respondents in the data, in panel A, and the sample used in our analysis, in panel B. The third row in panel B corresponds to our main sample of women when the outcome is knowledge by trimester. The last row in panel B corresponds to our main sample of 1,593 woman-pregnancies when the outcome is the month of detection. The small difference between these two last rows corresponds to women who were interviewed at some point during pregnancy when they did not know their status, but was not interviewed again; therefore they cannot be part of the sample when the outcome is the month of pregnancy detection.
