Baseline () characteristics of the study groups.

Parameter	HBS group n = 43	LBS group n = 42	value
Women/Men	30/13	29/13	0.943
Age (years)	55 (17)	55 (10)	0.725
Body weight (kg)	70.5 (19.3)	69.8 (17.9)	0.582
Height (m)	1.70 (0.12)	1.70 (0.10)	0.287
BMI (kg/m^2)	23.8 (4.51)	24.6 (5.63)	0.529
WC (cm)	85.0 (14.0)	83.5 (18.0)	0.519

Data are shown as median (IQR). HBS = high bicarbonate and sodium, LBS = low bicarbonate and sodium. BMI = body mass index, HC = hip circumference, WC = waist circumference, WHR = waist-to-hip ratio. Distribution of gender between groups was analyzed using the Chi-Quadrat test. All other group differences were assessed using unpaired t-test/Welch-test, or Mann–Whitney U test.
