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

The T-cell receptor (TCR) repertoire is a mirror of the human immune system that reflects processes caused by infections, cancer, autoimmunity, and aging. Next-generation sequencing has become a powerful tool for deep TCR profiling. Herein, we used this technology to study the repertoire features of TCR beta chain in the blood of healthy individuals.Peripheral blood samples were collected from 10 healthy donors. T cells were isolated with anti-human CD3 magnetic beads according to the manufacturer's protocol. We then combined multiplex-PCR, Illumina sequencing, and IMGT/High V-QUEST to analyze the characteristics and polymorphisms of the TCR.Most of the individual T cell clones were present at very low frequencies, suggesting that they had not undergone clonal expansion. The usage frequencies of the TCR beta variable, beta joining, and beta diversity gene segments were similar among T cells from different individuals. Notably, the usage frequency of individual nucleotides and amino acids within complementarity-determining region (CDR3) intervals was remarkably consistent between individuals. Moreover, our data show that terminal deoxynucleotidyl transferase activity was biased toward the insertion of G (31.92%) and C (27.14%) over A (21.82%) and T (19.12%) nucleotides.Some conserved features could be observed in the composition of CDR3, which may inform future studies of human TCR gene recombination.
