These were: older age (p < 0.001), diabetes (p < 0.001), hypertension (p < 0.001), pulmonary embolism (p = 0.015), cough (p = 0.005), high CRP (p < 0.001), high CO-RAD scale (p < 0.001), malaise (p = 0.017), dyspnea (p = 0.007) and high viral load (p < 0.001). Here, CRP is linked to hypertensive disorder.
