Laboratory parameters for the stroke population, according to the presence or absence of intracranial artery calcification (IAC)
| Parameter | All patients (n = 340) | No IAC (n = 81) | IAC (n = 259) | P |
|---|---|---|---|---|
| CKD | 92 (27.1) | 4 (4.9) | 88 (34.0) | <0.001 |
| Creatinine (μmo/L) | 94.6 ± 39.6 | 82.7 ± 16 | 98.3 ± 22 | 0.001 |
| GFR (ml/min/1.73m2) | 72.1 ± 21.7 | 82.2 ± 12.4 | 68.9 ± 17.9 | <0.001 |
| Fasting glucose (mM) | 5.7 ± 1.6 | 5.35 ± 1.1 | 5.82 ± 1.7 | 0.005 |
| LDL-c (g/L) | 1.24 ± 0.4 | 1.19 ± 0.4 | 1.37 ± 0.4 | 0.001 |
| CRP (log) | 1.2 ± 1.4 | 1.06 ± 1.2 | 1.22 ± 1.4 | 0.37 |
| Serum calcium (mM) | 2.26 ± 0.12 | 2.27 ± 0.2 | 2.25 ± 0.1 | 0.16 |
| Serum phosphate (mM) | 0.99 ± 0.2 | 1.0 ± 0.2 | 0.99 ± 0.2 | 0.64 |
| Haemoglobin (g/100 ml) | 14.1 ± 1.5 | 14.3 ± 1.6 | 14.0 ± 1.5 | 0.21 |
Results are presented either as means ± standard deviation or for CKD as n (%) with n = number of patients and % = percentage of patients in the group. NS, nonsignificant; GFR, glomerular filtration rate estimated using the four-component Modification of Diet in Renal Disease (MDRD) equation; LDL-c, low density lipoprotein cholesterol; CRP, C-reactive protein.
