Equipment is a property of the movement and is authored, never derived from the evidence corpus (docs/research/round2/ROUND2_KNOWN_CORRECTIONS.md §1). This option resolves to no catalogue exercise, so nothing has authored it yet.
R8's level field records who was eligible for the trial, not what a person needs before trying the practice, so it is not carried here.
The protocol remained consistent throughout the study, with no progression or regression noted. The participants practiced alternate nostril breathing for 15-20 minutes, 5 days a week, for 3 months without any changes in the technique.

No paper compares this option with another or calls it interchangeable with one.
A paper measuring one option against another does not make the two interchangeable, and it does not say which to choose. These are listed as what the papers did, and nothing here proposes a substitution.
