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).
