Figures 4 and 5 show the results of applying the criteria in the preceding paragraph to the data on both a coarse-grained and fine-grained time scale. The coarse-grained time scale provides an uncluttered view of the selection of significant SNPs by age ranges and suppresses inconsequential short-term variations in p-value. The fine-grained time scale provides plots of the effect sizes in a virtually continuous form, as well as indication of significance. The fine-grained time scale plot contains more information than the coarse-grained time scale plot but requires greater care in interpretation. For instance, many of the wiggles in the plot do not represent statistically significant variation of the effect sizes. Remarks on aspects of the results will refer to one or the other of the figures as appropriate.
