Incidence of perinatal death according to glucose categories for fasting, 1-hour and 2-hour moments of the 75 gr oral glucose tolerance test. Exact Cochrane-Armitage test for trend for overall perinatal mortality (fasting = 0.30; 1-hour = 0.05; 2-hour = 0.13) and for later perinatal mortality (fasting = 0.06; 1-hour = 0.01; 2-hour <0.01). To convert mg/dl to mmol/L divide by 18.02.
