Microcystic/Reticular Schwannoma Occurring in the Lumbar Spine: A Rare Case Report.
Article in Annals of African medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
abstractMicrocystic/reticular schwannoma (MRS) is a rare subtype of schwannoma characterized by distinctive histological features. It mainly occurs in the head-and-neck region and extremities. We present a case of MRS occurring in the lumbar spine, which is an exceedingly rare location for this tumor. This is the case of a middle-aged woman who presented with complaints of lower back pain radiating to the left lower limb. Magnetic resonance imaging demonstrated features suggestive of a myxopapillary ependymoma arising from the cauda equina at the L4-L5 vertebral level. Diagnosis of MRS was made based on the typical histopathological features and immunohistochemical positivity for the S100 marker. MRS is a rare subtype of schwannoma, which differs from classical schwannoma in several aspects. Raising awareness regarding this subtype is essential to budding pathologists to prevent their misdiagnosis as myxopapillary ependymoma.
