Analysis of nasal secretion culture results in diabetic patients with chronic rhinosinusitis and factors influencing postoperative recurrence.
Article in World journal of diabetes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIn diabetic patients, persistent hyperglycemia creates an optimal environment for the proliferation of pathogenic bacteria, resulting in severe complications. Consequently, chronic rhinosinusitis (CRS) complicated by diabetes is highly prevalent in clinical settings.
aimTo analyze the results of nasal secretion cultures in diabetic patients with CRS and identify the factors influencing postoperative recurrence.
methodsA retrospective analysis was conducted on the clinical data of 203 diabetic patients with CRS with nasal polyps who underwent the Messerklinger technique at Qingdao Hiser Hospital Affiliated of Qingdao University between January 2021 and January 2023. Preoperative nasal secretions were cultured to determine the types and distribution of pathogenic bacteria and assess antimicrobial susceptibility. Based on a one-year follow-up, patients were categorized into recurrence and nonrecurrence groups to analyze differences in their clinical data. Univariate and multivariate analyses were used to identify factors influencing postoperative recurrence.
resultsPathogens were detected in 153 of the 203 nasal secretion specimens collected from diabetic patients with CRS. A total of 134 pathogenic bacteria strains were isolated and identified, including 81 strains (60.4%) of gram-positive bacteria and 53 strains (39.6%) of gram-negative bacteria. Gram-positive bacteria exhibited relatively high resistance to penicillin G and erythromycin, while remaining highly sensitive to vancomycin, gentamicin, and rifampicin. Gram-negative bacteria demonstrated relatively high resistance to cefazolin and gentamicin, but showed high sensitivity to imipenem, meropenem, cefepime, and ceftazidime. Univariate analysis revealed statistically significant differences between the recurrence and nonrecurrence groups in fasting blood glucose levels, smoking history, Lund-Mackay scores, visual analog scale (VAS) scores, nasal septum deviation, allergic rhinitis, bronchial asthma, postoperative infection, long-term use of nasal decongestants, and adherence to medical prescriptions. Multivariate regression analysis identified fasting blood glucose levels and VAS-measured nasal symptom severity scores as independent factors influencing postoperative recurrence.
conclusionIn CRS patients with nasal polyps (CRSwNP), the detection rate of nasal pathogens is relatively high, and most of the isolated bacteria exhibit antimicrobial resistance. Additionally, the blood glucose level of patients with CRS combined with CRSwNP is a risk factor for postoperative recurrence.
