Why it matters in GWAS

Ad hoc filtering, subgrouping, or model changes introduced after inspecting results can improve diagnosis but also increase researcher degrees of freedom. Transparent labeling of ad hoc analyses helps readers separate confirmatory evidence from exploratory follow-up.

Example usage

"After the primary analysis, we ran an ad hoc sensitivity model excluding one recruitment center with atypical follow-up."

Related-term network

Click any node to open that term page.

Node order. The current term is first. Next come every page linked from Related terms, in the same top-to-bottom order as that list. Then new terms appear in two-hop layers: for each of those direct neighbors (in that same order), their related terms are appended if not already listed. A third pass does the same for two-hop nodes. The walk stops when a fixed maximum number of nodes is reached.
