The correlation (Spearman’s ρ; significance level p < 0.05) between the individual mean breathing amplitude of the right hemidiaphragm and age. The dashed line is the regression line. The crosses represent patients ≥ 5.5 years (Npat=56). Triangles and circles represent patients < 5.5 years treated with GA (Npat=12) and without GA (Npat=11), respectively.
