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
purposeEn bloc spondylectomy for spine tumors involves extensive removal of posterior vertebral elements, which are difficult to reconstruct. Often, the dura is left exposed, leading to scarring and adhesions which complicate revision surgeries. Synthetic barriers can be used to reduce adhesions, but they offer no structural support. Here, we present a novel technique using cadaveric femoral struts for posterior column reconstruction, creating a lamina-like structure spanning across the defect.
methodsWe conducted a retrospective institutional review of patients who underwent en bloc spondylectomy followed by reconstruction of the posterior elements using frozen cadaveric femoral struts. Allografts were contoured to fit adjacent spinous processes and secured with posterior instrumentation, creating a mechanical barrier with potential for osseous integration.
resultsNineteen patients (mean age: 52 years; 7 female) underwent the procedure for 14 primary and 5 metastatic tumors. Eight complications occurred, none related to the allograft. The construct aided in surgical re-exposure and protected the thecal sac during wound revisions. Of six patients with long-term follow-up CT scans, three showed allograft integration with solid fusion. Median follow-up was 27.6 months.
conclusionsFemoral allografts offer a simple, low-risk method for reconstruction of the posterior elements following spondylectomies, providing structural support and facilitating revision surgeries. Additional long-term data are needed to confirm their efficacy.
