Respiratory mechanics were measured in unchallenged WT and Cc16 −/− mice at 6 and 18 months of age in the using a FlexiVent device.
Data are mean ± SEM for data that are normally distributed or medians and interquartile ranges (IQR) for data that are not normally distributed (peripheral elastance values). Data were analyzed with ANOVAs (P < 0.001 for all parameters measured). Pair‐wise comparisons were performed using Student's t‐tests for data that are normally distributed or the Mann–Whitney U tests for data that are not normally distributed.
P < 0.05 between 6‐month‐old WT and Cc16 −/− mice.
P < 0.05 between 6‐ and 18‐month‐old WT mice.
P < 0.05 between 6‐ and 18‐month‐old Cc16 −/− mice.
P < 0.05 between 18‐month‐old WT and Cc16 −/− mice.
