How does blood sugar level affect wound infection rates and device revision and removal rates after hypoglossal nerve stimulation in obstructive sleep apnea patients? A large database study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis study aims to evaluate the impact of perioperative hyperglycemia on wound infection, device revision, reimplantation and removal rates after hypoglossal nerve stimulation, utilizing a large-scale and federated, real-world database.
methodsA retrospective cohort study was conducted using the TriNetX Network on September 26th, 2025. Patients with OSA who underwent HGNS implantation were classified into the hyperglycemic cohort if their laboratory glucose values exceeded the predefined thresholds (126 mg/dL and 154 mg/dL) during the six months before or after implantation. Otherwise, they were in non-glycemic cohort. Postoperative wound infection and device reoperation rates were assessed at one-year and three-year follow-up. Outcomes were analyzed using incidence rates, odds ratios (ORs), and Log-Rank tests, with propensity score matching (PSM) employed to control for confounding variables.
resultsPatients with serum glucose levels ≥ 126 mg/dL and ≥ 154 mg/dL exhibited significantly higher incidence rates of surgery-related wound infections compared to their respective counterparts (one-year OR: 1.56 and 1.82; three-year OR: 1.55 and 1.74; all p ≤ 0.01). These findings remained statistically significant after PSM (one-year OR: 1.51 and 2.08; three-year OR: 1.40 and 1.63; all p < 0.05). However, there were no significant differences, except 3 year OR after PSM, in device revision, replacement or removal rates at both one-year and three-year follow-ups (p > 0.05).
conclusionsHyperglycemia is associated with significantly increased risk of wound infection, including long term infection following HGNS implantation, while device reoperation rates remain unaffected. These findings underscore the importance of stringent perioperative glycemic control to mitigate postoperative infection risk in HGNS recipients.
