Lipid-Laden Alveolar Macrophages and pH Monitoring in Gastroesophageal Reflux-Related Respiratory Symptoms

Table 1

Regression analysis from pH-monitoring parameters correlated with LLAMs (% AMs) from BAL with patients stratified for RI > 5% or RI < 5% at distal channel recordings. No correlations could be found in these subgroups. 𝑃 values indicate no statistical differences for these correlations in patients with RI < 5% at distal channel recordings (n.s. = not significant).
