Association of estimated parameters with the chances of
different groups of clinical symptoms occurring over time
Association of sex, age, blood group type, baseline cortisol level, and
baseline aldosterone level with the chances of clinical symptoms
occurring over time are presented in Table 4. In terms of the
gastrointestinal and general categories of clinical symptoms, our
analysis indicated no association between any of the examined parameters
and the chances of symptoms occurring.
Meanwhile, we observed a significant relationship between baseline serum
cortisol and aldosterone levels with the chances of respiratory symptoms
occurring over time. Serum cortisol levels (OR= 0.937, P = 0.033)
had a decreasing effect on the outcome measure (chance of respiratory
symptoms occurring over time). However, serum aldosterone level (OR=
1.005, P = 0.020) had an increasing effect on the chance of
respiratory symptoms occurring over time. In the neurologic category of
symptoms, we saw a significant relationship between sex (OR= 0.530,P = 0.015) and the outcome variable. Over time, women are twice as
likely as men to develop neurologic symptoms.
