Figure 7. Human evidence from the UK Biobank.
(A and B) Relationship between age at death and number of chronic pain sites, in men (A) and women (B). Slanted lines were obtained from linear regression. Box‑and-whiskers show age distributions for each number of pain sites; gold dots indicate means. (C) Gene-level summary statistics for sex-stratified GWAS on number of chronic pain sites. Genes (nomenclature according to the Human Genome Organization [HUGO]) considered were the human analogs of mouse senescence-related genes shown in Figure 4. TP53 is the human analog of Trp53, encoding p53. N, sample size; ZSTAT, z statistic (MAGMA-assigned, gene-level summary test statistic; see Methods); P, 1-sided P value from test statistics; ZZ, difference between the men’s and women’s test statistics (men ZSTAT – women ZSTAT); ZZ_P, P value of ZZ, uncorrected; ZZ_FDR, false discovery rate–corrected P value of ZZ.
