[checklist name="variable_1" value="Is less than or equal to 7 days after the start of normal menses=1|Has not had sexual intercourse since the start of last normal menses=1|Has been correctly and consistently using a reliable method of contraception=1|Is less than or equal to 7 days after spontaneous or induced abortion=1|Is within 4 weeks postpartum=1|Is fully or nearly fully breastfeeding (exclusively breastfeeding or the vast majority - more than 85 percent - of feeds are breastfeeds), amenorrheic, and less than 6 months postpartum=1"]
Score --> [calc memo="number" value="score=(variable_1)"] out of 6 items
Interpretation --> [calc memo="result" value="score2=(variable_1);score2>0?'Can be reasonably certain that patient is not pregnant without a pregnancy test':'Cannot be reasonably certain that patient is not pregnant without a pregnancy test'"]
[checkbox memo="display/hide references" name="variable_2" value=""][conditional field="variable_2" condition="(variable_2).isNot('')"]
