Details
This table indicates which substances were screened in each trial.
The first column (substance) is drawn from labels which appear in case
report forms for the three clinical trials. The remaining three columns
hold "NO" if a substance was not screened in that trial, or a grouping
label indicating what type of drug was screened. The ungrouped data can be
found in all_drugs.
For example, "Opiate 300 ng" and "Oxycodone" are assigned to the
grouping label "Opioid", and they were assessed in each clinical trial
(so none of the rows show "NO"). In contrast, while "Opiate 2000 ng" is
also assigned to the grouping label "Opioid", it was neither assessed in
ctn_0027 nor ctn_0030; thus, the grouping label is "NO" for these trials.

Harmonization Information vignette.
