Multiple linear regression - Human prefrontal cortex development.

FS = FS cell index. CSP = Corticospinal projection neuron index. AST = Astrocyte index. The first 3 tables show simple linear regression of 3 maturation indices (FS cell index, Corticospinal projection neuron index, and Astrocyte index) on parvalbumin expression levels in data from developing human prefrontal cortex. In all cases there was a highly significant relationship between index measurements and parvalbumin expression levels (p<0.0001). The fourth table shows results when all three indices were entered in the same model. Only the FS cell index remained significantly associated with parvalbumin expression levels (p<0.002).
