CRP and cancer: Bronchiectasis (OR = 27.52, p <0.001), superinfections (OR = 4.18, p <0.001), cancer (OR = 3.05, p <0.001), haematological malignancies (OR = 4.69, p <0.001) and active cancer treatment (OR = 5.53, p <0.001), ischemic heart disease (OR = 2.27, p = 0.042), length of hospital stay (OR = 1.20, p <0.001), CRP (OR = 1.08, p <0.001) and PCT (OR = 1.24, p = 0.030) were the nine variables significantly associated with an increased likelihood of admission to s-ICU/ICU.
