Characteristics of the group of LKDs and age- and sex-matched controls from the 1 % representative Czech population sample

	LKDs	Czech population sample	p value
Number (men/women)	42 (28/14)	42 (28/14)	ns.
Age (years)	51.96±10.36	51.57±9.77	ns.
BMI (kg/m 2 )	26.73±3.10	29.24±6.11	p<0.05
Non-HDL-C (mmol/l)	3.37±0.96	3.95±1.12	ns.
HDL-C (mmol/l)	1.35±0.43	1.57±0.41	ns.
Triglycerides (mmol/l)	1.72±0.96	1.28±0.58	ns.

BMI: body mass index; non-HDL-C: non-high-density lipoprotein cholesterol, HDL-C: high-density lipoprotein cholesterol, ns: non-significant. Characteristics of the whole LKDs group compared with the Czech population sample. The number, age, BMI, non-HDL-C, triglyceride and HDL-C concentrations of the group of LKDs were compared with those of a representative sample of the Czech population whose age- and sex-matched individuals were selected from a population study analyzing a 1 % representative Czech population sample aged 25–64 years [34]. The total numbers of women and men were 28 and 14, respectively. Values are expressed as mean ± SD.
