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

Macroscopic hematuria concomitant with acute pharyngitis is a characteristic feature of immunoglobulin A nephropathy (IgAN). Although the underlying mechanism of worsening hematuria has not been fully elucidated, activation of the innate immune system of nasopharynx-associated lymphoid tissue is thought to play an important role. The epipharynx is an immunologically activated site even under normal conditions, and enhanced activation of innate immunity is likely to occur in response to airborne infection. As latent but significant epipharyngitis presents in most IgAN patients, it is plausible that acute pharyngitis due to airway infection may contribute as a trigger of the epipharyngeal innate immune system, which is already upregulated in the chronically inflamed environment. The aim of this review was to discuss the mechanism of epipharynx-kidney axis involvement in glomerular vasculitis responsible for the worsening of hematuria in IgAN.
