In this article by Shim et al., the measurement unit of CSF cell count was given incorrectly. It should be “cells/mm³” instead of “cells/cm³”.

Corrected sentences are as follows;

Page 570 Results of abstract :

Cell counts (median : 8 vs. 1 cells/mm³) and protein levels (median : 68 vs. 17 mg/dL) significantly higher in lumbar CSF than in ventricular CSF (p<0.001).

Page 571 (right column), line 46–53 :

The mean total cell count in the lumbar CSF was 25.0 cells/mm³ (standard deviation : ±47.3; range : 0–310). The reference normal range was set at ≤5 cells/mm³. The distribution of the cell count had a leftward skew (median : 8 cells/mm³; third quartile : 25 cells/mm³) (Fig. 1A). The distribution of the cell counts in the ventricular CSF was also skewed (mean : 10.4 cells/mm³; standard deviation : ±44.2; range : 0–360; median : 1 cells/mm³; third quartile : 5 cells/mm³) (Fig. 1B).

Page 573 (left column) line 5 :

(median: 2 vs. 9 cells/mm³; p=0.046).

Page 574 (right column) line 1–2 :

the ventricular CSF (1 cell/mm³) was within the normal range and that 75% of the patients had ≤5 cells/mm³.
