^aCounts of nuclei stained by Hoechst 33342 dye.

^bCounts of nuclei stained by Hoechst 33342 dye minus counts of nuclei stained by Hoechst and EtHD. Fisher’s exact test p < 10⁻⁵, odds ratio 0.576 (“small” effect size).

^cCounts of nuclei not stained by EtHD but positive for Hoechst 33342 and FITC fluorescence. Fisher’s exact test p < 10⁻¹⁵, odds ratio 3.118 (“moderate” effect size).

^dPercent is live nuclei vs. all nuclei.

^ePercent is live with FITC vs. live without FITC.

^f50 μM H₂O₂.
