1 · What the graph read from it

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.

2 · The registry

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

backgroundObstructive sleep apnea (OSA) is a prevalent sleep disorder associated with intermittent hypoxia, oxidative stress, and systemic inflammation, posing risks for adverse postoperative outcomes, including surgical site infections (SSIs). Elderly patients undergoing posterior lumbar interbody fusion (PLIF) are particularly susceptible to SSIs due to advanced age, comorbidities, and prolonged surgical times. However, the role of OSA in increasing SSI risk among this population remains unclear.

methodsThis retrospective cohort study analyzed 478 elderly PLIF patients from a single institution between May 2016 and June 2024. Of these, 113 were diagnosed with OSA. Propensity score matching (PSM) was performed to balance baseline characteristics, resulting in 83 matched pairs. SSI rates, hospital stays, and readmission rates were compared between the OSA and non-OSA groups. Subgroup analysis was conducted to evaluate the effects of continuous positive airway pressure (CPAP) or automatic positive airway pressure (APAP) therapy on postoperative outcomes.

resultsAfter PSM, OSA patients demonstrated a significantly higher SSI incidence (13.3% vs. 3.6%, p = 0.04) compared to non-OSA patients. On multivariate analysis, OSA was the only factor that remained significantly associated with an increased risk of SSIs (Odds Ratio = 4.509, 95% CI: 1.283-21.504, p = 0.03). OSA patients also experienced longer hospital stays (10.1 ± 2.9 vs. 9.1 ± 2.0 days, p = 0.01) and elevated 30-day readmission rates (9.6% vs. 1.2%, p = 0.02). Subgroup analysis revealed that CPAP/APAP therapy reduced SSI incidence (3.9% vs. 17.5%, p = 0.08) and shortened hospital stays (9.1 ± 1.5 vs. 10.5 ± 3.2 days, p = 0.03) among OSA patients.

conclusionOSA significantly increases the risk of early SSIs and prolongs hospital stays in elderly PLIF patients. Subgroup analysis suggests that CPAP/APAP therapy may have benefits to OSA patients, though this association requires validation through prospective studies. These findings emphasize the importance of preoperative OSA screening and management to improve surgical outcomes in this high-risk population.
