Epidemiological features, lesion location, clinical features, and outcome data stratified by the occurrence of pneumonia

No pneumonia (n = 56)Pneumonia (n = 44)p Value
Data are given as mean (SD) or n (%).
Numbers of NIHSS items refer to severe clinical findings (corresponding to individual NIHSS scores of 2 or more). In case of “hemiparesis,” numbers of the NIHSS items “motor arm” and “motor leg” were added; hemiparesis was counted as severe if the sum score was ⩾6.
F, female; M, male; NIHSS, National Institutes of Health stroke scale.
