CRP and lung disorder: In the multivariate calculations, results remained robust for age (difference per year of 2 mmol/l, [95% CI 0 to 4], p = 0.016), NRS score ≥ 5 points (difference pre point of 61 mmol/l, [95% CI 6 to 117], p = 0.031), CRP (difference per 10 unit increase of 13 mmol/l, [95% CI 10 to 17], p = < 0.001), creatinine (difference per unit increase of 3 mmol/l, [95%CI 1 to 5], p = 0.015), and a main diagnosis of lung disease (difference − 109 mmol/l, [95% CI [-211 to -7], p = 0.036).
