Table 2 A GCS values throughout the study duration. B Comparison between GCS values among study group (n = 30) throughout study duration

From: The use of dexamethasone therapy for conservative management of chronic subdural hematomas: a question about efficacy and safety

GCS	Day 1 (n = 30) (%)	Day 14 (n = 30) (%)	1 month (n = 30) (%)	3 months^# (n = 29) (%)	6 months^# (n = 29) (%)
8	0 (0.0)	0 (0.0)	1 (3.3)	0 (0.0)	0 (0.0)
13	16 (53.3)	2 (6.7)	1 (3.3)	0 (0.0)	0 (0.0)
14	11 (36.7)	17 (56.7)	8 (26.7)	2 (6.9)	0 (0.0)
15	3 (10.0)	11 (36.7)	20 (66.7)	27 (93.1)	29 (100.0)

Comparison	Chi-square test	p-value
Day 1 vs. Day 14	16.746	< 0.001**
Day 1 vs. 1 M	27.274	< 0.001**
Day 1 vs. 3 M	41.426	< 0.001**
Day 1 vs. 6 M	48.122	< 0.001**
Day 14 vs. 1 M	7.186	0.066
Day 14 vs. 3 M	20.568	< 0.001**
Day 14 vs. 6 M	27.091	< 0.001**
1 M vs. 3 M	6.628	0.085
1 M vs. 6 M	11.639	0.009*
3 M vs. 6 M	0.518	0.472

Using: Chi-square test
GCS Glasgow Coma Scale, n number of patients, M months after protocol initiation
p-value > 0.05 is insignificant, *p-value < 0.05 is significant, **p-value < 0.001 is highly significant
^#one case was deceased
