Best practice

When reporting data, specify the units (in this case, "years") clearly to avoid ambiguity. For instance, instead of saying "the study duration was 5", say "the study "duration in years" was 5".

Common error

Avoid using just "duration" without specifying the units. Always clarify whether the duration is in days, months, or "years" to prevent misinterpretation. For example, avoid writing "treatment duration was long", instead specify "treatment "duration in years" was long."
