The Need for Postoperative Chest X-Ray After Placement of Hypoglossal Nerve Stimulator.

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
objectiveHypoglossal nerve stimulation (HGNS) is a surgical treatment for obstructive sleep apnea (OSA) in patients intolerant to CPAP. Current practice often involves chest x-ray (CXR) in the postanesthesia care unit (PACU), though the incidence of pulmonary complications is low. This study evaluates the necessity of immediate postoperative CXR after HGNS placement.
methodsWe conducted a retrospective chart review of 361 patients who underwent unilateral HGNS placement from 2014 to 2021 at a single institution. Surgeries were performed by two high-volume sleep surgeons. Data collected included demographics, preoperative sleep study results, postoperative CXR findings, and subsequent management. Logistic regression calculated odds ratios (ORs) for the association between abnormal CXR findings and patient characteristics, with mean differences and 95% confidence intervals (CIs) for continuous variables.
resultsAbnormal CXR findings occurred in five patients (1.4%), including two pneumothoraxes (0.6%) and three pulmonary edemas (0.8%). Patients with abnormal CXR findings had increased odds of reporting respiratory symptoms in the PACU compared to those without (OR: 3.8, 95% CI: 1.1-13.2, p < 0.001) and required extended postoperative stays. All patients with pulmonary edema had respiratory symptoms before CXR confirmation. No significant demographic or clinical differences were found between patients with normal and abnormal CXR findings.
conclusionThis study confirms the low incidence of pulmonary complications following HGNS placement by high-volume surgeons. Immediate CXR may not be necessary in asymptomatic patients. However, routine postoperative imaging in the recovery period is warranted to document hardware placement. LEVEL OF EVIDENCE: 4:
