Table 5 Threshold effect analysis of the relationship between the serum 25(OH) D concentrations and UL in the unadjusted model and adjusted logistic regression models

From: U-shaped association between serum 25-hydroxyvitamin D concentrations and urinary leakage among adult females aged 45 years and over in the United States: a cross-sectional study

 

OR (95% CI) P Value

Serum 25(OH)D concentrations

Unadjusted model a

Adjusted model b

25(OH) D < 63.5

0.995 (0.991, 0.998) < 0.01

0.993 (0.989, 0.996) < 0.01

25(OH) D ≥ 63.5

1.008 (1.006, 1.010) < 0.01

1.007 (1.005, 1.009) < 0.01

  1. a Unadjusted model represent Crude model including 25(OH) D;
  2. b Adjusted model adjusted for sociodemographic variables (including age, race, education, income and BMI), drink, smoke, diabetes, hypertension, hyperlipidemia, pregnant and vaginal deliveries history
