Using a multivariable regression model, we show that CD160 expression on less than or equal to 37.1% (25th percentile of non-recurrent melioidosis patients) NK cells is an independent correlate of recurrent melioidosis infection, when controlling for age, sex, BMI, diabetes status, and pre-existing liver and renal disease (adjusted Odds ratio 1.67 (95% CI 1.20–3.46), p = 0.0447; Table S2). The gene discussed is CD160; the disease is diabetes mellitus.
