The quantitative analysis confirmed that drainage to the nasal cavity was significantly reduced in the ciliopathy FOXJ1-Cre;CEP164fl/fl mice as shown in Fig. 3M: (CEP164fl/fl (N = 7): 11.3 ± 4.2 mm3 vs FOXJ1-Cre;CEP164fl/fl (N = 8): 6.7 ± 2.7 mm3, mean difference = 4.6 mm3 95% CI [0.4, 8.9] mm3, p-value = 0.034). This evidence concerns the gene FOXJ1 and ciliopathy.
