Table 2 A binary logistic regression investigation of the relationship between different independent variables (age, BMI, parity) and the dependent variable bone mineral density normality that is converted to a binary scale (normal, abnormal)
From: Quantitative ultrasound assessment of the effect of parity on bone mineral density in females
Dependent variable: bone mineral density normality (0 = below average, osteoporosis or osteopenia, 1 = normal) | ||
|---|---|---|
Odds ratio (confidence interval) | p-value | |
Age (years) | 1.022 (0.932–1.121) | 0.6 |
BMI (kg/m2) | 1.078 (0.989–1.175) | 0.1 |
Parity (0 = nulliparous, 1 = multiparous) | 0.187 (0.043–0.824) | 0.03* |
