CRP and bronchiectasis: A multivariate analysis was performed to verify the most important factors associated with the occurrence of ≥2 exacerbations (or required 1 hospitalization because AECOPD) during the previous year, showing that CONUT score ≥ 5 was the best independent predictor (OR 20.740, p < 0.001), followed by the presence of a BMI < 25 kg/m2 (OR 17.154, p = 0.001), bronchiectasis (OR 11.886, p = 0.031), and plasma CRP levels (OR 1.668, p < 0.001), as shown in (Figure 4).
