Autoimmune Retinopathy Caused by Anti-Paraneoplastic Antigen MA2: A Case Study.
Article in Case reports in ophthalmology. 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
Autoimmune retinopathy is a cause of unexplained visual impairment and visual field impairment, which are often related with life-threatening cancers. Here, we report a case of autoimmune retinopathy positive for anti-paraneoplastic antigen MA2 (PNMA2) antibody in serum. Visual acuity and field were impaired, and OCT and ERG were performed. No abnormalities were observed in OCT, but a marked decrease in pyramidal response was observed in ERG. Paraneoplastic antigen-related antibodies in the serum were tested, and PNMA2 was positive. Systemic evaluation to search for the presence of cancer was conducted by specialists treating cancer. However, cancers were not detected, but bladder and prostate cancer were identified 3 years later, and anti-PNMA2 antibodies were again positive in the serum. Although there have been no reports on PNMA2-related retinopathy, the possibility of the paraneoplastic syndrome should be kept in mind when retinopathy of unknown cause is observed.
