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
purposeJuvenile xanthogranuloma (JXG) presenting as solitary vertebral body lesion is infrequently seen and usually limited to one or two levels. We report a case of an isolated JXG with extensive cervical spinal (bony and extradural) involvement in a 6-year-old child. There was a diagnostic dilemma as the radiologic and intraoperative picture resembled tuberculosis. The spinal reconstruction was also challenging due to involvement of multiple vertebral levels and necessitated an anterior C1 screw.
methodsThe lytic lesion was multicompartmental, involving the craniovertebral junction and the subaxial spine (till C6 vertebral body) and extending into the retropharyngeal space. Noticeably, an associated thoracic syringomyelia was also present. Near-total excision of the lesion and 360° spinal fixation was performed using fibular strut graft. The graft was cranially anchored to the C1 anterior arch, thereby sharing the load with the posterior occipito-cervical instrumentation in order to avoid a construct failure due to cantilever effect.
resultsAt 12-month follow-up, the patient had good clinico-radiologic outcome with evidence of bony fusion and resolution of syrinx.
conclusionThe report highlights the diagnostic dilemma of JXG lesion on both the radiology and surgery and discusses the challenges in the management and the relevant literature. The described technique can be a viable option in pediatric tumors with extensive C2 vertebral body involvement. Occasionally, extradural compression can have associated syrinx formation and the primary treatment per se could tackle the underlying syringomyelia.
