Small cell carcinoma presenting as ocular paraneoplastic syndrome due to CRMP-5.
Article in Neurosciences (Riyadh, Saudi Arabia), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
We report the case of a lady who presented with 3 weeks of visual floaters and optic disc swelling. Subsequent investigations revealed deep white matter changes on brain imaging, and enlarged mediastinal nodes. The presence of anti-CRMP-5 antibodies finally led to the diagnosis of a paraneoplastic syndrome, and mediastinal lymph node biopsy confirmed the diagnosis of small-cell lung cancer. The learning points from this case include that optic neuritis can be the only presenting feature of a paraneoplastic neurological syndrome, and the usefulness of anti-neuronal antibody measurement as a diagnostic marker of an underlying paraneoplastic disease process. The great challenge is to recognise these tumour-associated autoimmune system presentations early, as they often appear long before the primary cancer is evident. Prompt treatment leads to an earlier reduction in circulating auto-antibody possibly due to reduction in tumour size, and thus less likelihood of permanent neuronal damage.
