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

backgroundIn humans, there is a 4:1 male:female ratio in the incidence of abdominal aortic aneurysms (AAAs). c-Jun-N-terminal kinase (JNK) is an important upstream regulator of several enzymes involved in AAA formation, including the matrix metalloproteinases (MMPs). The purpose of this study was to determine if there is a gender difference between males and females in JNK during AAA formation. MATERIALS AND

methodsMale and female C57/B6 mice underwent aortic perfusion with elastase or heat inactivated elastase with aortas harvested at d 3 and 14 for phenotype determination, RT-PCR, Western blot, and zymography. Additionally, in vitro experiments using siRNA were conducted to define JNK regulation of matrix metalloproteinases (MMPs). A t-test was used to compare between groups.

resultsMales formed larger AAAs at d 14 compared with females (P < 0.001), with significantly higher levels of JNK1 protein, proMMP9, proMMP2, and active MMP2. At d 3, males had more JNK1 mRNA, protein, and MMP activity. Knockdown of JNK 1 or 2 in vitro decreased MMP activity, while knockdown of JNK 1 and 2 together blocked all MMP activity.

conclusionAlterations in JNK between genders is partially responsible for the differential rates of experimental AAA formation, likely through differential regulation of MMPs.
