Every ARA-290 vial against its label
One dot per vial, placed by how much it held compared with the amount on the label.
Dot chart of 2 vials (every ARA-290 vial on file), each placed by its measured amount compared with the label, from 50% under to 50% over. 0 are within 5% of the label, 2 are 5 to 20% under or more than 5% over, 0 are more than 20% under or more than 50% over, and 0 were empty.
