Are non-visualized pregnancy losses prognostically important for unexplained recurrent miscarriage?
Non-visualized pregnancy losses contribute negatively to the chance for live birth: each non-visualized pregnancy loss confers a relative risk (RR) for live birth of 0.90 (95% CI 0.83; 0.97), equivalent to the RR conferred by each additional clinical miscarriage.
Findings suggest that building a greenway did not affect the physical activity behaviors of proximate residents. Other studies should consider different trail types from a variety of settings to determine whether physical activity behavior changes may be context specific.
