From the study's abstract: "Studies of planned home births attended by registered midwives have been limited by incomplete data, nonrepresentative sampling, inadequate statistical power and the inability to exclude unplanned home births. We compared the outcomes of planned home births attended by midwives with those of planned hospital births attended by midwives or physicians." and "We included all planned home births ... and all planned hospital births meeting the eligibility requirements for home birth that were attended by the same cohort of midwives ... We also included a matched [my emphasis] sample of physician-attended planned hospital births (n = 5331)."
