DESeq2 design to predict fasting glucose

Question

[adR]

Hi all, What I do usually in DESeq2 design is as follow (dds <- DESeqDataSetFromMatrix (countdata = countData, coldata= colData, design = ~ FBG)). If I am correct, this means genes are predicted by variable fasting blood glucose (FBG). However, If I want consider fasting glucose as response variable and genes as predicting variable, the design should be the same or different?. Best, Amare
