Synthetic teaching example of TP53 RNA abundance. Six independent biological units per group; points with mean and SD. Two-sided Welch tests compare each drug with Control; Holm correction across both planned comparisons. CIs are unadjusted 95% intervals for the mean difference. Only Holm-adjusted P < 0.05 is annotated; the full table retains all results. Plot area: 50 x 50 mm; the export includes labels at their original font sizes.
