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
objectiveTo evaluate the efficacy of intraoperative gentamicin versus vancomycin-loaded PerOssal (Osartis, Münster, Germany) carriers on interbody fusion rates and infection control in patients undergoing surgery for pyogenic spondylodiscitis.
methodsThis retrospective study included 29 patients with pyogenic spondylodiscitis who underwent surgical debridement, interbody fusion, and pedicle screw fixation between February 2018 and March 2023. Patients received PerOssal carriers loaded with either gentamicin (Group A, n = 14) or vancomycin (Group B, n = 15). Clinical outcomes, including fusion rates, infection control, complications, and inflammatory markers, were analyzed.
resultsBaseline characteristics between groups were comparable. Fusion rates at 3-6 months' follow-up were 92.8% (13/14) in Group A and 80.0% (12/15) in Group B, without significant differences (P > 0.05). Both groups showed significant reductions in white blood cell counts and C‑reactive protein levels postoperatively, without inter-group differences (P > 0.05). Complications included cerebrospinal fluid leakage, hematoma, pulmonary embolism, and wound infections, all managed successfully with no recurrent infections observed.
conclusionIn the short term, PerOssal carriers loaded with either gentamicin or vancomycin demonstrated effective infection control for pyogenic spondylodiscitis and high interbody fusion rates. Moreover, no apparent adverse effects on bone healing were associated with the local administration of high-concentration antibiotics.
