To measure fatigue, fatigue questionnaire containing 9 <strong>\u200e<\/strong>questions eliciting the subject\u2019s feeling in scales of 1 to 7, getting a possible score of 9 to <strong>\u200e\u200e<\/strong>63, and Visual Analogue Scale <strong>\u200e<\/strong>in which nurses specified their fatigue in a band of zero to 10 were used. <strong>\u200e<\/strong>The 25-hydroxyvitamin D, which is the most important vitamin D metabolite, also was determined.
