While the\n                      <jats:italic>NOS3<\/jats:italic>\n                      rs1799983 variant is known to impair endothelial function, data regarding its genotypic and allelic frequency and association with hypertension in Indonesian rural populations remains limited. The present study aimed to investigate the genotypic and allelic frequency of\n                      <jats:italic>NOS3<\/jats:italic>\n                      rs1799983 and examine its association with hypertension across multiple ethnic groups in rural Indonesian populations.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials &amp;amp; methods<\/jats:title>\n                    <jats:p>\n                      This population-based case-control study included 798 individuals with hypertension and 448 subjects with normal blood pressure from four primarily rural Indonesian regions: Papua, Pamijahan, Morotai, and Natuna. Genotyping of the\n                      <jats:italic>NOS3<\/jats:italic>\n                      rs1799983 variant was performed using real-time polymerase chain reaction. Multiple logistic regression models were employed to evaluate the association between genotypes and hypertension.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In the pooled population, no significant unadjusted categorical association existed between the NOS3 variant and hypertension (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.069). Subgroup analysis revealed a nominal unadjusted association in Morotai under the dominant model (OR\u2009=\u20091.675,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.017), which lost statistical significance following false discovery rate (FDR) correction (adjusted\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.051). Numerically, GT\u2009+\u2009TT carriers exhibited significantly higher mean systolic blood pressure (SBP) in the Morotai normotensive control group, an effect that survived FDR correction (adjusted\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.016). Conversely, unadjusted SBP elevations among GT\u2009+\u2009TT carriers within the hypertensive cohorts (overall\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.024; Morotai\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.016) became non-significant after FDR correction (adjusted\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.064). Crucially, after adjusting for confounders using multivariate analysis, the GT\u2009+\u2009TT genotypes emerged as an independent predictor of increased hypertension risk in both the pooled population (aOR\u2009=\u20091.392, 95% CI: 1.045\u20131.853,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.024) and the Morotai subpopulation (aOR\u2009=\u20092.056,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.002).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>\n                      The T allele of the\n                      <jats:italic>NOS3<\/jats:italic>\n                      rs1799983 variant was rare in the studied populations.
