From model 1 and 2, all variables except TSH were entered into the model regardless of their significance before TSH was input with stepwise method (P < 0.10 and > 0.05 as thresholds for inclusion and exclusion). For model 3, all variables were input equally with stepwise method. BMI, body mass index; DBP, diastolic blood pressure; NI, not included as candidate variables from the beginning; SBP, systolic blood pressure.

Standardized β coefficient.

Male is valued as 1 and female as 2 when the variable “gender” was included as an independent.
