Why it matters in GWAS

Many studies contribute hazard ratios or age-stratified incidence patterns; harmonising time-to-event phenotypes across cohorts affects comparability with binary GWAS and influences choice of summary statistics for meta-analysis.

Example usage

"The phenotype file listed age at event and censoring status for a time-to-event GWAS in UK Biobank."

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.
