High-throughput sequencing analysis of genes encoding the B-lymphocyte receptor heavy-chain CDR3 in renal and peripheral blood of IgA nephropathy.
Article in Bioscience reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
aimIgA nephropathy (IgAN) is one of the most common chronic glomerulonephritis. Its etiology and pathogenesis remain unclear. We thus explored the immune repertoire of the B-cell receptor (BCR) and the heavy-chain complementarity-determining region 3 (CDR3) in renal tissue and peripheral blood of IgAN patients.
methodTotal RNAs extracted from renal tissues and peripheral blood of patients and peripheral blood of healthy controls (HCs) were analyzed via high-throughput multiplex PCR sequencing. We amplified and sequenced BCR heavy-chain CDR3 regions to explore repertoire diversity, V/J gene family distribution, CDR3 lengths, BCR heavy-chain variants, consistency between tissue and peripheral blood data, and clones 'shared' by these bodily compartments.
resultsWe identified the renal tissue and peripheral blood BCR heavy-chain CDR3 immune repertoires of 15 IgAN patients. Top1 could be more readily cloned from peripheral blood of patients than from controls (P<0.05), the average CDR3 length was significantly shorter in patients than in HCs (P<0.05), the variant frequency of the gene encoding the BCR heavy chain was higher in patients than in HCs (P<0.05), and the BCR variant frequency was highest in IgAN kidney tissue. Preliminary screening for 'shared' clones showed that, in at least 13 patients, the 'ALYFHNSAY', 'ARWGPMYYYMDV', 'ARDQGALNA', and 'ARVDNPADF' CDR3 sequences were evident in peripheral blood samples from patients, but not HCs.
conclusionsWe found that the 'ALYFHNSAY', 'ARWGPMYYYMDV', 'ARDQGALNA', and 'ARVDNPADF' clonal sequences may be useful for noninvasive diagnosis and treatment planning in IgAN.
