Relationship between the levels of CSF glucose/HbA1c and the severity of GBS.

<p><b>(A)</b> 191 patients with available laboratory data of glucose in CSF were divided into two groups. Patients with CSF glucose concentration higher than 4.1 mmol/L fell into the high CSF glucose group, and the others into the normal CSF group. A high level of CSF glucose appeared in the patients who demonstrated cranial nerve involvement, hypoesthesia and autonomic deficits (3.90 mmol/L, 3.93 mmol/L and 3.87 mmol/L vs 3.68 mmol/L, 3.68 mmol/L and 3.67 mmol/L) (<i>p</i> < 0.05). <b>(B)</b> Relationships between CSF glucose concentration and the MRC sum score at nadir were measured by the linear regression (R² = 0.03, <i>p</i> = 0.469). <b>(C)</b> The logistic regression was done to examine the relationship between the CSF glucose concentration and the GBS disability scale score (R² = 0.003, <i>p</i> = 0.449). <b>(D)</b> The logistic regression was performed to explore the relationship between the HbA1c proportion and the GBS disability scale score (R² = 0.029, <i>p</i> = 0.377).
