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

Interleukin-7 (IL-7) and the IL-7 receptor (IL-7R) have been shown to be alternatively spliced in infectious diseases. We tested IL-7 and IL-7R splicing in a tuberculosis (TB)-vaccine/Mycobacterium tuberculosis (Mtb)-challenge model in non-human primates (NHPs). Differential IL-7 splicing was detected in peripheral blood mononuclear cells (PBMCs) from 15/15 NHPs showing 6 different IL-7 spliced isoforms. This pattern did not change after infection with virulent Mtb. We demonstrated increased IL-7 (6 exon) and IL-17 protein production in lung tissue along with concomitant decreased transforming growth factor-β (TGF-β) from NHPs (vaccinated with a recombinant BCG (rBCG)) who showed increased survival after Mtb challenge. IL-7 increased IL-17 and interferon-γ (IFN-γ) gene and protein expression in PBMCs. Mtb-infected NHPs showed differential IL-7R splicing associated with the anatomical location and tissue origin, that is, in lung tissue, hilus, axillary lymph nodes (LNs) and spleen. Differential splicing of the IL-7R was typical for healthy (non-Mtb infected) and for Mtb-infected lung tissue with a dominant expression of soluble IL-7R (sIL-7R) receptor lacking exon 6 (9:1 ratio of sIL-7R/cell-bound IL-7R). Differential ratios of cell-bound vs sIL-7R could be observed in hilus and axillary LNs from Mtb-infected NHPs with an inversed ratio of 1:9 (sIL-7R/cell-bound IL-7R) in spleen and PBMCs. Soluble IL-7R is exclusively present in lung tissue.
