CASP6 and hydrops fetalis: While the correlation between ASC and CASP-6 was weak (rS = 0.41) and not significant (p = 0.07) as well as the correlation between ASC and cGSDMD (rS = 0.44, p = 0.053), the correlation between the total number of CASP-6 immunoreactive neurons per squared millimeter of HF tissue significantly positively correlated with the total number of cGSDMD immunoreactive neurons (rs = 0.57, p = 0.009, Figure 2C).
