Anti-Zic4 Paraneoplastic Cerebellar Degeneration With Mesial Temporal Lobe Hyperintensity in a Patient With Papillary Thyroid Carcinoma: A Case Report and Review of the Literature.
Article in Cureus, 2023. 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
Paraneoplastic cerebellar degeneration (PCD), a subtype of paraneoplastic neurological syndromes (PNSs), is a rare autoimmune neurologic syndrome that usually develops secondary to an underlying malignancy. We present a 49-year-old patient that developed PCD secondary to occult papillary thyroid carcinoma. The patient had progressive difficulty ambulating for 3 years. A neurological exam revealed signs of cerebellar syndrome. Brain magnetic resonance imaging (MRI) showed significant cerebellar atrophy and mesial temporal lobe hyperintensity. Immunological testing was highly positive for anti-CV2 and anti-Zic4 onconeural antibodies. Positron emission tomography (PET)/Computerized tomography (CT) scan revealed significant hypermetabolic uptake of F-18 fluorodeoxyglucose (FGD) by a left thyroid nodule. Histological examination of the nodule was positive for papillary thyroid carcinoma, confirming the diagnosis of PCD. A trial of high-dose methylprednisolone failed to improve the patient's symptoms. This case highlights the importance of maintaining high suspicion for PCD while investigating cases of cerebellar degeneration. Early detection is essential to prevent irreversible damage in affected patients.
