Fig 1. The distribution of LPS-neutralizing capacity (LPS-NC) of stroke cases and controls.

Serum samples of cases (n = 98) and controls (n = 100) were spiked with 3.67 EU/ml of E. coli LPS and the LPS-neutralizing capacity of the serum was calculated as $(1-[\frac{\mathrm{L}\mathrm{P}\mathrm{S}\mathrm{s}\mathrm{p}\mathrm{i}\mathrm{k}\mathrm{e}\mathrm{d}}{\mathrm{L}\mathrm{P}\mathrm{S}\mathrm{i}\mathrm{n}\mathrm{t}\mathrm{a}\mathrm{c}\mathrm{t}+3.67\frac{EU}{ml}}\left]\right)\mathrm{*}100\mathrm{\%}$.
