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 report an unusual titanium mesh cage failure after ten years of follow-up. CLINICAL CASE: A 40-year-old woman diagnosed with low-grade spinal chondrosarcoma underwent a total en-bloc spondylenctomy (TES) surgery. This technique required a wide resection, anterior reconstruction with a titanium mesh cage (TMC), and posterior stabilization. For several years a favorable clinical outcome was achieved. After 10 years of follow-up, the patient developed acute non-traumatic low back pain without neurological repercussions. The images confirmed a rupture of the titanium cage. After ruling out tumor recurrence, the patient went through spinal instrumentation revision.
conclusionIsolated TMC rupture is a rare event scarcely reported in the literature. There is a strong recommendation to instrument two levels proximal and distal to the bone defect in 360° reconstructions after a TES. Stability had likely been lost over the years due to the slow resorption of the bone graft. We consider necessary studies with a higher casuistry and level of evidence to analyze the contributing factors for the event of TMC rupture.
