MATERIALS AND METHODS
Local ethics committee approval was obtained for the study. In this study, 101 patients who applied to Ordu State Hospital dermatology outpatient clinic between March 2019 and June 2020 and were diagnosed with zona zoster and had a vitamin D result at the time of diagnosis and a control group of 100 people were included. Data of the patient and control groups were recorded. The location of the disease and the season of admission were recorded in the patient group. Individuals with cardiovascular disease, gastrointestinal disease, kidney disease, malignancy, pregnancy, diabetes mellitus, autoimmune and inflammatory diseases, and individuals taking vitamin D supplements were not included in the control group. Informed consent was obtained.
The data were evaluated with IBM SPPS statistics 21 package program. Numerical variables were expressed as mean ± standard deviation, percentage. An evaluation was made after checking whether the parameters were normally distributed. In data analysis, student’s T test was used for group comparisons, and in cases where there was no normal distribution, Mann Whitney-U test was used. The relationship between the two variables was evaluated using the Pearson correlation test in parametric tests and the Spearman correlation test in non-parametric tests. A value of p <0.05 was accepted for the significance level of the tests.
