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

objectiveHistamine plays a role in several (patho) physiological processes that are commonly studied in mouse models. However, a systematic quantification of histamine and its metabolite N-methylhistamine in mouse organs has not been reported so far.

methodsBalb/c and C57Bl/6 mice were grouped according to their sex and age. Brains, hearts, lungs, livers, kidneys, stomachs, intestines, thymi, spleens, and lymph nodes were excised, weighed, and homogenized. Histamine and N-methylhistamine were quantified simultaneously by a HPLC-mass spectrometry method.

resultsIn all organs analyzed, histamine and N-methylhistamine were detected; however, with quantitative differences. Histamine was present most abundantly in the stomach, lymph nodes, and thymus. The lowest histamine concentrations were detected in brain, liver, lung, and intestine. In most organs, the histamine concentrations increased age-dependently. Substantial concentrations of N-methylhistamine were detected only in lung, intestine and kidney, while in all other organs it was present only in minor quantities.

conclusionHPLC-mass spectrometry is a useful method for the highly sensitive and simultaneous detection of histamine and N-methylhistamine. Histamine is present in virtually all organs, not only in those traditionally associated with histamine-mediated disease. Highest concentrations are found in stomach, lymph node, and thymus; medium concentrations in heart, spleen, and kidney; and lowest concentrations detected in intestine, brain, liver, and lung.
