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

objectiveTotal parenteral nutrition (TPN), with the complete removal of enteral nutrition, results in marked changes in intestinal intraepithelial lymphocyte (IEL) function and phenotype. Previous work shows that TPN results in a loss of intestinal epithelial cell-derived interleukin-7 (IL-7), and this loss may play an important role in development of such TPN-associated IEL changes.

methodsTo further understand this relation, we generated a transgenic mouse (IL-7), which overexpresses IL-7 specifically in intestinal epithelial cells. We hypothesized that this localized overexpression would attenuate many of the observed TPN-associated IEL changes.

resultsOur study showed that TPN administration led to significant changes in IEL phenotype, including a marked decline in the CD8alphabeta+, CD4+, and alphabeta-TCR+ populations. IEL basal proliferation decreased 1.7-fold compared with wild-type TPN mice. TPN administration in wild-type mice resulted in several changes in IEL-derived cytokine expression. IL-7 mice given TPN, however, maintained IEL proliferation, and sustained normal IEL numbers and phenotype.

conclusionsWe conclude that specific intestinal IL-7 overexpression significantly attenuated many IEL changes in phenotype and function after TPN administration. These findings suggest a mechanism by which TPN results in observed IEL changes.
