How to read this: 0 means the source explicitly assigned zero. “Not listed” means the source did not provide a score for this medication. Scores from different scales are not averaged.
How to interpret the evidence
6 of 7 public source versions contain an explicit medication-list entry for codeine.
The available rows for codeine display the same numeric value. Agreement of the displayed numbers does not establish identical methods, clinical meaning or patient-level risk.
None of the public rows in this profile is an explicit zero. An unlisted source still supplies no value.

What this page does not establish
- No medication-list entry is available here from Yamada-ABS 2023. These gaps remain “Not listed”; no score is inferred from another source or from class membership.
- No route inference unless present in the source label.
- These source records do not estimate an individual’s probability of harm or establish whether to start, stop or change a medication. Ordinal source scores are not averaged into a UnifiedACB score.
