Therefore, we performed partial correlations (controlling for the effect of hypertension and/or cardiopathy) between the selected hippocampal subfields volume and adjMMSE (Extended data, Table S2 A),41 as well as between blood Sulfiredoxin-1 (SRXN1) mRNA levels and selected hippocampal subfields volume and adjMMSE in CD individuals (Extended data, Table S2 B).41 The results obtained with hypertension, cardiopathy, and both hypertension and cardiopathy as control variables, were very similar to those obtained previously using bivariate correlations. Here, SRXN1 is linked to hypertensive disorder.
