Gumusyayla2017RTurkeyAdultsNLR were found to be significantly higher in GBS patients participating in the study than healthy volunteers. In addition, NLR was positively correlated with the Hughes score and negatively correlated with the MRC sum score calculated at the time of admission and three months after admission.6
Sahin2017RTurkeyAdultsNLR was a predictor of facial diplegia in GBS patients. Also, NLR had a statistically significant correlation with MRC and NCS findings such as distal latency, main F latency, conduction velocity, and amplitude.6
Kim2019RKoreaChildrenNLR was not different between GBS patients with full recovery and those with functional deficit after treatment.6
Tunc2019RTurkeyAdultsNLR was significantly correlated with HDS at the end of the first month after GBS.7
