Measure | Adjusted OR (95% CI) | ||||
---|---|---|---|---|---|
No APO (n = 3185) | Any APO (n = 909) | HDP (n = 544) | Spontaneous preterm birth (n = 199) | SGA (n = 170) | |
NT-proBNP, median (IQR), pg/mL | 63.0 (41.0-95.0) | 56.0 (35.0-89.0) | 52.0 (34.0-83.0) | 61.0 (33.0-104.0) | 61.0 (39.0-95.0) |
NT-proBNP, per doubling in value | 1 [Reference] | 0.90 (0.82-0.98)c | 0.81 (0.73-0.91)c | 1.00 (0.85-1.18) | 1.04 (0.87-1.25) |
NT-proBNP, per doubling in value, controlling for systolic blood pressure | 1 [Reference] | 0.91 (0.84-1.00)c | 0.84 (0.75-0.94)c | 1.00 (0.84-1.18) | 1.05 (0.88-1.26) |
Abbreviations: HDP, hypertensive disorders of pregnancy; OR, odds ratio; SGA, small for gestational age.
Adjusted for age, race and ethnicity, body mass index, smoking, and aspirin use.
This characteristic is included in statistical models after a logarithm transformation (base, 2). ORs for log-transformed quantities are interpreted on the multiplicative scale.
