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 peptide transporter PEPT2 mediates cellular uptake of di- and tripeptides driven by an inwardly directed electrochemical proton gradient. In mammals PEPT2 is found in a variety of organs such as kidney, lung, brain, enteric nervous system, and mammary gland. Highest expression levels are observed in renal proximal tubules where PEPT2 contributes to reabsorption of filtered di- and tripeptides. To assess the physiological importance of the transporter in overall metabolism, we have generated a Pept2-/- mouse line that lacks a functional PEPT2 protein. Here we present data on body weight, organ weights, and blood pressure. Mice were then fed diets containing either 10, 20, or 30% (w/w) protein, and food and water intake rates as well as plasma and urine parameters were determined. In spite of PEPT2 expression in a variety of tissues, only subtle phenotypic changes were observed. Male PEPT2 null mice displayed lower bodyweight and lower relative heart weight, whereas, relative kidney weight was lower in female Pept2-/- mice. No differences were found in blood pressure. When fed diets with different protein contents, Pept2-/- mice adapted food intake to dietary protein content with higher consumption rates on low protein and reduced food intake rates on the high protein diet.
