We’ve selected a locally grown paper for discussion in journal club this week, India’s Janani Suraksha Yojana, a conditional cash transfer programme to increase births in health facilities: an impact evaluation, by Lim et al, with a focus on the methods: the paper has “used three analytical approaches (matching, with-versus-without comparison, and differences in differences) to assess the effect of JSY on antenatal care, in-facility births, and perinatal, neonatal, and maternal deaths.”

This generated quite a list of follow-up readings:
A cool application:
American Academy of Pediatrics: Janet Elise Rosenbaum, Patient Teenagers? A Comparison of the Sexual Behavior of Virginity Pledgers and Matched Nonpledgers, Pediatrics, Vol. 123 No. 1 Jan 2009.
What’s Known on This Subject
Two studies have found, by using regression, that virginity pledges delay sex, but regression cannot correct for large preexisting differences between pledgers and nonpledgers.
What This Study Adds
We used a more robust method than regression to compare virginity pledgers with similar nonpledgers and found virtually no difference in sexual behavior or STDs and much less use of condoms.
A validation environment that calls the method into questions
