VTE: venous thomboembolism, COPD: chronic obstructive pulmonary disease, BMI: body mass index.
† Active cancer, cancer surgery or cancer treatment at present.
§ Immobility prior to admission due to lower limb paresis or paralysis.
¥ Reduced mobility (rest in bed or a chair for over 50% of the time, and not moving further than the toilet).
‡ The frequency of risk factors surpasses the total number of patients, as some subjects had more than one risk factor. No patient with inherited prothrombotic states were found in the analyzed group. One patient in the anticoagulated group had a history of a prothrombotic condition.
