| S6 | [AHRQ/NCBI research-gap framework](https://www.ncbi.nlm.nih.gov/books/NBK126702/) | U.S. evidence-synthesis method | Characterize where evidence falls short and why: insufficient/imprecise, biased, inconsistent/unknown, not right information; distinguish gaps from decision-relevant needs | Research evidence context, not organizational maturity |
| S7 | [AHRQ Gap Analysis Facilitator's Guide](https://www.ahrq.gov/patient-safety/settings/hospital/candor/modules/facguide3.html) | U.S. health quality agency | Document review, focus groups, structured interviews, priorities, report template | Healthcare program context |

Do not cite S2-S7 as if they establish one universal gap-analysis standard. They are complementary examples of a recurring method in different domains.
