Hi @Rsimmonds,
Great! If the new columns you added have sample designations, for example:

| sample-id | group     | age   |
|-----------|-----------|-------|
| S1        | healthy   | child |
| S2        | healthy   | child |
| S3        | healthy   | adult |
| S4        | treatment | adult |
| S5        | treatment | teen  |
| S6        | treatment | teen  |

Then alph-agroup significance will run a Kruskal-Wallis test using your new columns as grouping maps. So you will see boxplots comparing health vs treatment samples, and if you use the drop-down menu from the top of the plot, you can select the other group say age, and then you’ll see boxplots comparing the 3 age categories.
