CRP and cystic fibrosis: Table 2 shows the correlation coefficients and the p-values estimated using Spearman correlation. αCGRP concentration was not correlated with BMI, CRP, IgG, and FEV1. At the same time, the results of the correlation between CGRP and age, white blood cell count, and neutrophil count, although not reaching statistical significance, are close to p = 0.05, indicating that further analysis is required across a larger number of CF patients.
