1 · What the graph read from it

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.

2 · The registry

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

Clonal expansions of CD8+ T cells have been identified in muscle and blood of polymyositis patients by PCR techniques, including T cell receptor (TCR) complementarity-determining region (CDR)3 length analysis (spectratyping). To examine a possible pathogenic role of these clonally expanded T cells, we combined CDR3 spectratyping with laser microdissection and single-cell PCR of individual myocytotoxic T cells that contact, invade, and destroy a skeletal muscle fiber. First, we screened cDNA from muscle biopsy specimens by CDR3 spectratyping for expanded TCR beta chain variable region (BV) sequences. To pinpoint the corresponding T cells in tissue, we stained cryostat sections with appropriate anti-TCR BV mAbs, isolated single BV+ T cells that directly contacted or invaded a muscle fiber by laser-assisted microdissection, and amplified their TCR BV chain sequences from rearranged genomic DNA. In this way, we could relate the oligoclonal peaks identified by CDR3-spectratype screening to morphologically characterized microdissected T cells. In one patient, a large fraction of the microdissected T cells carried a common TCR-BV amino acid CDR3 motif and conservative nucleotide exchanges in the CDR3 region, suggesting an antigen-driven response. In several cases, we tracked these T cell clones for several years in CD8+ (but not CD4+) blood lymphocytes and in two patients also in consecutive muscle biopsy specimens. During immunosuppressive therapy, oligoclonal CDR3-spectratype patterns tended to revert to more polyclonal Gaussian distribution-like patterns. Our findings demonstrate that CDR3 spectratyping and single-cell analysis can be combined to identify and track autoaggressive T cell clones in blood and target tissue. This approach should be applicable to other inflammatory and autoimmune disorders.
