Number of patients with

• Pneumonia: Clinical or radiological diagnosis. or
• Pulmonary embolism: Radiological diagnosis. Signs of pneumonia or pulmonary embolism in the autopsy

Number of patients with new-onset of acute stroke, defined as a new focal or generalised neurological deficit of >24h duration in motor, sensory, or coordination functions with compatible brain imaging and confirmed by a neurologist. Transient ischemic attack is not considered as acute stroke. Signs of stroke in the autopsy.

Number of patients with new-onset of acute kidney injury, defined according to the AKIN classification as AKI stage ≥2.

This means increase of creatinine >2-3x from baseline within the hospital stay. Or urine output less than 0.5 ml kg-1 per hour for more than 12 hours. Or signs of acute kidney injury in the autopsy.
