From: Meta-analysis of NAD(P)(H) quantification results exhibits variability across mammalian tissues

Effect of pre- versus post-mortem tissue collection on NAD(H) levels in normal rats and mice liver. a-d: Reported (a) NAD+, (b) NADH, (c) total NAD(H) levels, and (d) NAD+/NADH ratio in young (< 18 months old) control rat liver samples harvested at different timepoints relative to sacrifice. (e): NAD+ levels in young (< 14 months old) control mouse liver samples harvested at different timepoints relative to sacrifice. Boxes represent 25th and 75th percentile with median line. Whiskers show min. to max. values. Statistical significance was determined by one-way ANOVA with multiple comparisons using Tukey’s test as post hoc test, setting P < 0.05 (*) and P < 0.005 (**) as significant. Ω: Overall effect of harvest timepoint relative to sacrifice.
