Sporadic inclusion body myositis: Diagnostic value of p62 immunostaining.
Article in Medicina clinica, 2019. 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
BACKGROUND AND
objectivesSporadic inclusion body myositis (sIBM) diagnosis is frequently delayed or confused with another class of disorders, and misdiagnosis is common. Sometimes, we have problems diagnosing an sIBM in the early stages or predicting when a PM is going to become an sIBM. In this sense, we believe that p62 immunostaining could help clinicians. CASE REPORT: We report the case of a 61-year-old patient with sIBM who six years earlier had been diagnosed with polymyositis (PM). After muscle biopsies analyses, we showed the natural history of sIBM by p62 expression.
resultsWhen we looked for p62 aggregates retrospectively we could see small dotted p62 aggregates in the muscle fibres of the first muscle biopsy. Six years later, the patient presented with the typical clinical picture of sIBM, also the muscle biopsy was characteristic, with large p62 aggregates.
conclusionsProbably p62 immunostaining could help to distinguish PM patients that are going to become sIBM, but to date there has been no systematic study to clarify p62 utility in myositis.
