Characteristics of pathogenic bacteria and pharmacological surveillance of postoperative hospital-acquired infections in gynecologic malignancies: A single-center observational study.
Observational study in Medicine, 2026. 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
Postoperative hospital-acquired infection in gynecologic malignancies is a severe complication, and improper treatment can affect the recovery and survival of patients. In this study, we analyzed the characteristics and distribution of pathogenic bacteria and their drug resistance in postoperative nosocomial infections in gynecologic malignancies to provide reliable guidance for clinical pharmacological monitoring. A total of 103 patients with postoperative infection following a gynecologic malignant tumor matching the inclusion criteria were selected from those who visited the gynecologic oncology department of Ganzhou Cancer Hospital/Ganzhou Cancer Center. On the day of hospital infection diagnosis, the patients' secretions were collected and subjected to bacterial culture and drug-sensitivity tests before administering antibacterial medications. Furthermore, the distribution of pathogenic bacteria and drug-resistance characteristics of hospital infections were analyzed. A total of 127 pathogenic strains were cultured from 103 patients. The urinary tract, surgical incision site, genital tract, and pelvis were the primary infection targets, with the infection rates of 31.07%, 26.21%, 18.45%, and 11.65%, respectively. While 87.80% of Escherichia coli strains were resistant to ampicillin and methicillin/sulfamethoxazole, 100.00% and 60.00% of Klebsiella pneumoniae demonstrated resistance to ampicillin and tetracycline, respectively. All Staphylococcus epidermidis strains resisted cefotaxime, ceftriaxone, cefazolin, cefuroxime, erythromycin, benzocillin, and penicillin, while 83.34% of them showed resistance to ampicillin and methicillin/sulfamethoxazole. All Staphylococcus aureus strains were resistant to penicillin. Postoperative hospital-acquired infections following gynecologic malignancies are characterized by a diverse array of pathogenic bacteria with high drug resistance. A comprehensive assessment of the infectious condition is required with the assistance of a clinical pharmacist, accompanied by a scientific and suitable treatment plan for the patient based on the results of the drug-sensitivity test and monitoring of adverse reactions during treatment. The treatment strategy can be modified at any time during the treatment after considering pathogenic evidence and adverse drug effects to improve clinical efficacy.
