Headache determines quality of life in idiopathic intracranial hypertension

Table 3 Correlation between changes in the 36-item short form health survey domains and changes in headache disability, severity and frequency following the therapeutic diet

Domain	Headache disability (Headache impact test-6 score)	Headache severity (Visual analogue pain scale)	Headache frequency (days/week)
Physical functioning	-0.67	-0.74	-0.48
Physical functioning	p=0.001	p=0.001	p=0.052
Role limitation due to physical problems	-0.70	-0.71	-0.53
Role limitation due to physical problems	p < 0.001	p=0.002	p=0.029
Role limitation due to emotional problems	-0.71	-0.78	-0.38
Role limitation due to emotional problems	p < 0.001	p < 0.001	p=0.14
Social functioning	-0.81	-0.62	-0.60
Social functioning	p < 0.001	p=0.014	p=0.015
Mental health	-0.64	-0.65	-0.46
Mental health	p=0.003	p=0.009	p=0.075
Energy/Vitality	-0.79	-0.70	-0.42
Energy/Vitality	p < 0.001	p=0.004	p=0.11
Pain	-0.66	-0.59	-0.60
Pain	p=0.002	p=0.018	p=0.010
General health perception	-0.67	-0.68	-0.49
General health perception	p=0.002	p=0.006	p=0.056
Change in health	-0.58	-0.39	-0.63
Change in health	p=0.007	p=0.13	p=0.007
Physical component score	-0.59	-0.57	-0.55
Physical component score	p=0.007	p=0.027	p=0.027
Mental component score	-0.88	-0.73	-0.45
Mental component score	p < 0.001	p=0.002	p=0.082

If a Bonferroni correction were applied to account for the multiple domains of the SF-36, the p value is reduced to p < 0.0045, but this might represent an over correction.
