Inverse probability of treatment weighting was used to balance all baseline characteristics. Cox proportional hazards regression was used to evaluate the hazard of incident diabetes associated with parathyroidectomy.<\/jats:p><\/jats:sec>Results<\/jats:title>A total of 3135 patients with PHPT were included (596 [19.0%] surgical and 2539 [81.0%] nonsurgical). The mean (SD) age was 67.5 (14.2) years, and 2211 (70.5%) individuals were female. A total of 518 patients in the nonsurgical group developed incident diabetes during a median (IQR) follow-up of 2.2 (0.9-4.3) years, compared to 156 patients in the surgical group during a median (IQR) follow-up of 5.5 (3.3-8.0) years. Parathyroidectomy was associated with lower risk of incident diabetes (hazard ratio [HR], 0.68 [95% CI, 0.65-0.71]; P<\/jats:italic>\u2009&amp;lt;\u2009.001). Results were consistent across multiple sensitivity analyses. Subgroup analyses revealed more prominent protective associations among younger patients (age \u226465 years vs &amp;gt;65 years: HR, 0.64 [95% CI, 0.60-0.68] vs HR, 0.68 [95% CI, 0.63-0.72]; interaction P<\/jats:italic>\u2009&amp;lt;\u2009.001) and those with more severe PHPT (parathyroid hormone [PTH] &amp;gt; twice the upper limit of normal vs PTH \u2264 twice the upper limit of normal: HR, 0.58 [95% CI, 0.53-0.63] vs HR, 0.73 [95% CI, 0.69-0.77]; calcium &amp;gt; 2.8 vs calcium \u2264 2.8 mmol\/L : HR, 0.58 [95%CI, 0.54-0.63] vs HR, 0.69 [95%CI, 0.66-0.73]; interaction P<\/jats:italic>\u2009&amp;lt;\u2009.001).<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>In this cohort of patients with PHPT, parathyroidectomy was associated with a lower risk of incident diabetes.
