Background: Multi-center trials enable the recruitment of

larger study samples, although results might be influenced

by site-specific factors. Methods: Site differences of a multicenter

prospective double-blind, double-dummy randomized

controlled trial (7 centers: Central Europe (Vienna)/USA

(3 urban/3 rural centers)) comparing safety and efficacy of

methadone and buprenorphine in pregnant opioid-dependent

women and their neonates. Results: Urban US women

had the highest rate of concomitant opioid (p = 0.050) and

cocaine consumption (p = 0.003), the highest dropout rate

(p = 0.001), and received the lowest voucher sums (p = 0.001).

Viennese neonates had significantly higher Apgar scores

1 min (p = 0.001) and 5 min after birth (p ! 0.001) and were

more often born by cesarean section (p = 0.024). Rural US

newborns had a significantly shorter neonatal abstinence

syndrome treatment duration compared to Viennese and

urban US sites (p = 0.006), in addition to other site-specific

differences, suggesting a more severely affected group of

women in the urban US sites. Conclusion: This clinical trial

represents a role model for pharmacological treatment in

this unique sample of pregnant women and demonstrates

the clinical importance of considering site-specific factors in

research and clinical practice.
