Protocol Option Count Tool

Description

Count distinct available protocol options.

Research ethics review involves evidence, participants, governance and context as well as record completeness. Role counts, disclosure presence and weighted criterion terms can organize supplied assertions; a complete checklist or numerical score does not itself determine ethical acceptability or valid authority.

Count distinct available protocol options.

Limitations and assumptions

Option meaning, genuine choice, protocol suitability and ethical acceptability are not evaluated.
Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.

Alternative or Complementary methods

Review the original protocol, evidence and governance requirements with the responsible ethics body and qualified professionals for substantive decisions.
