CVD Associations for hemoglobin decline, high early hemoglobin and the effect of co-adjustment

		95% CI*
Model†	HR‡	Lower	Upper
Model #1
Hemoglobin decline§ only	1.8	1.14	2.71
Model #2
High early hemoglobin∥only	1.4	1.00	1.90
Model #3
Hemoglobin decline	1.6	1.04	2.54
High early hemoglobin	1.3	0.89	1.84

^*95% CI=95% Confidence Interval (Lower limit, Upper limit).

^†All models were adjusted for age, race and parity. Age is represented continuously. Parity is represented using two dummy variables for primiparas and multiparas with 3 or more prior live births versus else. Race is represented using two dummy variables for African-Americans and Asians versus else.

^‡HR=Hazard Ratio.

^§Hemoglobin decline is defined as the lowest decile of hemoglobin change between the 2nd and 3rd trimesters.

^∥High early hemoglobin is defined as the highest quartile based on the distribution of all first measures in the 2nd trimester.
