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

Many proteins have been proposed to act as surrogate markers of organ damage, yet for many candidates the essential biomarker characteristics that link the protein to the injured organ have not yet been described. We generated an Ngal reporter mouse by inserting a double-fusion reporter gene encoding luciferase-2 and mCherry (Luc2-mC) into the Ngal (Lcn2) locus. The Ngal-Luc2-mC reporter accurately recapitulated the endogenous message and illuminated injuries in vivo in real time. In the kidney, Ngal-Luc2-mC imaging showed a sensitive, rapid, dose-dependent, reversible, and organ- and cell-specific relationship with tubular stress, which correlated with the level of urinary Ngal (uNgal). Unexpectedly, specific cells of the distal nephron were the source of uNgal. Cells isolated from Ngal-Luc2-mC mice also revealed both the onset and the resolution of the injury, and the actions of NF-κB inhibitors and antibiotics during infection. Thus, imaging of Ngal-Luc2-mC mice and cells identified injurious and reparative agents that affect kidney damage.
