Odds ratios for developing gestational diabetes mellitus in relation to visceral adipose tissue depth measured by ultrasonography at about 14 weeks’ gestation.

Measure	Unadjusted odds ratio (95% confidence interval)	Adjusted odds ratioa (95% confidence interval)
Visceral adipose tissue depth (per 1-cm unit increase)	1.99* (1.59–2.46)	2.00** (1.61 to 2.50)

*p = 0.001; **p = 0.001.

^aAdjusted for pre-pregnancy body mass index (continuous, in kg/m²) and maternal age (continuous, in 1-year increments).
