Tuberculous spondylodiscitis following intravesical Bacille Calmette-Guérin therapy: A case report and systematic literature review.

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
Background: Intravesical Bacille Calmette-Guérin (BCG) therapy is the standard treatment for non-muscle-invasive bladder cancer. Disseminated BCG infection occurs in fewer than 5% of patients, with skeletal involvement (i.e., tuberculous spondylitis) being reported in only 36 cases worldwide. Here, a 77-year-old male with a history of BCG therapy for non-muscle-invasive bladder cancer developed L1/L2 osteomyelitis treated with percutaneous endoscopic transforaminal discectomy, debridement, and anti-tuberculous therapy. Twelve months later, however, the patient required, posterior instrumentation from T10-L5 and anterior column reconstruction at L1-2. Case Description: A 77-year-old male with a history of intravesical BCG therapy for non-muscle-invasive bladder cancer presented with a 2-month history of severe low back pain, focal lumbar tenderness, but no neurological deficits. He was afebrile and the C-reactive protein was elevated (3.0 mg/dL). The lumbar Magnetic resonance imaging (MR) demonstrated L1/2 spondylodiscitis with bilateral psoas muscle nodular lesions suspicious for abscesses. The computed tomography confirmed destructive changes at the L1 inferior endplate and a fracture line through the left L2 pedicle. The patient underwent a percutaneous endoscopic transforaminal discectomy with debridement. The tuberculosis Polymerase chain reaction (PCR) returning positive while TB interferon-gamma release assay (T-SPOT) remained indeterminate. Anti-tuberculous therapy (isoniazid, rifampicin, and ethambutol; pyrazinamide excluded due to Conclusion: This represents the 37
