A Case of Frosted Branch Angiitis in the Age of Polymerase Chain Reaction: Diagnostic and Therapeutic Considerations.
Article in Cureus, 2022. 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
To describe a unique case highlighting the limitations and caveats of multiplex polymerase chain reaction (mPCR) in the diagnosis of posterior infectious uveitis, specifically frosted branch angiitis (FBA), we present a case of FBA in which multiple diagnostic modalities, including mPCR, are inconclusive. A thorough literature review was carried out to discuss the validity of mPCR in the setting of posterior infectious uveitis, the theoretical effect of sample dilution, and to explore a management strategy in these difficult cases. It is known that mPCR has high sensitivity and specificity, with a low false negative rate. However, the rate of false negatives appears to increase in cases of FBA, and when samples are diluted. In such cases we suggest empiric treatment be initiated and targeted towards microorganisms most likely to be implicated based on exam and history.
