Fig 5. Nitric Oxide (NO) production ratio.

Dotted line represents a 1:1 ratio in which each mouse strain has equivalent NO production. Purple diamond depicts the ratio between low- (LA) and high-active (HA) mice showing that for every one unit of NO produced by HA mice, the LA mice produce 0.64 units of NO. This suggests HA mice have higher NO production. Data are expressed as mean (95% CI). Statistics are by t-test with alpha level set at p≤0.05.
