Mean time taken to read the sample labels and prototype labels plotted against the label print size

The characteristics of the print for each label are shown. For the samples, the values are plotted in order of average print size for the instructions, drug name and patient name going from smallest to largest font size. When these averages were the same, they were further ordered in terms of font size for 1) the instructions, 2) drug name and 3) patient name. All were printed in all capitals unless there is an “S,” which indicates sentence case. The asterisk indicates label 9. For the prototypes, all instructions were printed in sentence case. “U” indicates that the instruction numbers were in uppercase words. “L” indicates the numbers in lowercase words, “UH” represents the numbers written in uppercase words with highlighting, and “N” indicates they were written in numerals.
