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.
