Also, we needed the patients to have a measurable degree of headache before treatment.
Remembering characteristics of headaches occurring several years prior to EVT may pose a considerable challenge to some patients, which can result in some degree of headache diagnosis inaccuracy.
However, he did not divide the headache into subtypes, and the degree of headache with first onset of migraine may be confounded by recall bias in our study, potentially leading to this discrepancy.
In accordance with guidance for controlled trials, [11] the degree of headache severity was rated on a 4-point scale to indicate severe (3), moderate (2) or mild (1), or headache-free (0).
Some patients experienced some degree of headache on the day of the injection, but no other side effects were reported [ 69].
Secondary outcome variables include the following: headache intensity, headache-associated symptoms, medication used, cost of medication, health care utilization, change in general health status, study credibility, degree of headache related disability (MIDAS), and satisfaction with care.
The MIDAS questionnaire can also be used to stratify adult patients into groups with different treatment needs according to the degree of headache-related disability.
However, onset and presentation of migraine in patients with a first-degree family history of headache was significantly earlier than those with no family history (U = 3533.5, p = 0.003, r = −0.19 and U = 2871.5, p<0.001, r = −0.26 respectively; see figure 2).
Significant positive relationships were observed between the prevalence of several symptoms (headache, nausea, eye and throat irritation) and both frequency of odor perception and degree of worry.
In the present study, most of the patients did not have regular contact with their own PCP or neurologist which at least to some degree, explain why the burden of headache was still high after 4 years with a mean of 18.4 headache days/month and HI/month of 321.
