<p class="MsoNormal">Unless I'm mistaken, Desk Checks aren't mentioned in the study design at all. Trace tables are basically the same, and while I've certainly seen versions that have the line numbers on the side, I feel like they are redundant. I usually
do Trace Tables (desk checks) like the diagram on the RHS *(in your example), with the bottom-most values representing the current value of the variable.<o:p></o:p></p>
