UPP1 and ischemic stroke: Figure S1 shows the means and standard deviations of APOA1-UP/LRP ratios in hyperacute phase (0–12 h), acute phase (>12–24 h), and subacute phase (>24–72 h) of ischemic stroke. The serum level of APOA1-UP was stable during the first 72 h of acute onset of ischemic stroke (p = 0.2156).
