The relation between the number of risk factors and the number of weeks of delivery. The preterm birth rate (preterm birth/total birth ratio) was 7.7% (2/26) in the patients without risk factors (a history of lupus nephritis and pre-pregnancy serum C3 level < 85 mg/dl), 39.0% (16/41) in those with 1 risk factor, and 66.7% (8/12) in those with 2 risk factors. The greater the number of these risk factors, the higher was the preterm birth rate (P = 0.0007)
