Associations and variance explained by different variables. (a) Decreasing protein abundance levels (NPX) with longer storage time, (b) Increasing abundance levels (NPX) with longer storage time. (c) Fraction of variance explained by storage time (all proteins with nominally significant associations, Supplementary Table 1). (d) Increasing protein abundance levels (NPX) for CUB domain-containing protein 1 (CDCP1) with age after storage-time component removed (linear model). (e) Same as (d), but decreasing with increased age of individual for Neurotrophin-3 (NT-3). (f) Fraction of variance explained by age in the residuals after correcting for storage time (all proteins with nominally significant associations, Supplementary Table 2).
