  1. **Some supporting literature, i.e., ≥ 2 supporting studies.
  2. *Limited supporting literature, i.e., <2 supporting studies.
  3. -Results not obvious, i.e., the only supporting study used mixtures of NP and MP, or showed mixed effects within the same study;
  4. ?Controversial, where conflicting results were provided by different studies.
