IGF1 and Stroke: In the present study, we investigated the potential associations between pre-stroke PA and post-stroke s-IGF-I, at baseline (baseline s-IGF-I) and at 3 months post-stroke (3-month s-IGF-I), and including the change in s-IGF-I calculated between these two time-points (ΔIGF-I), and we examined whether these associations were retained in different multiple linear regression models.
