Results
Table 1 shows the comparison results of biochemical, hormonal, and hematological parameters of participants in living and deceased groups. As shown in Table 1 , WBC, neutrophils, and monocytes were significantly different in the two groups (p <0.001), and its values were lower in the living group than in the deceased group. Lymphocytes were significantly different between the two groups (p <0.001) and were higher in the living group than in the deceased group. Hb and PLT were also significantly different (p =0.043 and p <0.001) in the two groups and were lower in the living group than the deceased group. MPV median values do not differ according to prognosis (p = 0.994). While the median value was 9.9 in the survivors, it was obtained as 10 in the deceased.
RDW, CRP, and glucose were significantly lower in the living group than in the deceased group (p <0.001). Alb and Ca values were significantly higher in the live group than in the deceased group (p <0.001). K (p = 0.019), LDH (P <0.001), and UREA (P <0.001) were significantly lower in the living group than in the deceased group. Na was significantly higher in the living group than in the deceased group (P =0.011). Creatinine, Procalcitonin, Ferritin, and the number of hospitalization days in living patients were significantly lower than in patients who died (p <0.001). Finally, median values of D-dimer (mg / L) differ according to prognosis (p <0.001). While the median value was 0.63 in the survivors, it was found as 4.38 in the deceased. Based on the obtained values, the risk factors affecting the death of each variable were investigated, and the results are shown in Table 2 .
As Table 2 shows, increasing age increases the risk of death by 1.044 (p <0.001). The risk of death in men is 2,242 times higher than in women (p <0.001). An increase in WBC value increases the risk of death by 1,335, while an increase in neutrophils increases the risk of death 1.4 times (p <0.001). PLT increases 1.005 times, RDW increases 1.361 times, CRP 1.019, Glucose 1.01, LDH 1.008, Urea 1.042, creatinine 3.87, ferritin 1.003, D-Dimer 1.075, and hospitalization time increased the risk of death by 1.133 times. Lymphocyte, Monocyte, HB, MPV, K, Na, and PCR positivity were not determined as independent risk factors for death (p> 0.05).
Median age values differ according to the groups (p <0.001). While the median age for the survivors was 69 years, it was determined as 74 years for those who died (Table 3 ). In a total of 424 cases included in the study, the rate of women was 47.2%, while the rate of men was 52.8%. While the rate of death in females is 32%, it is 51.3% in males, and there is a statistically significant difference between these rates (p <0.001).
