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

Although it is now recognized that low levels of reactive oxygen species (ROS) are required for the mitogenic response, mitogen-induced signalling pathways that regulate ROS generation in non-phagocytic cells remain largely uncharacterized. Using a real-time assay for measuring hydrogen peroxide (H(2)O(2)) formation, we analysed H(2)O(2) release in human HaCaT keratinocytes in response to lysophosphatidic acid (LPA), a mitogen for keratinocytes. LPA rapidly increased H(2)O(2) release in HaCaT cells. Unlike LPA-induced mitogen-activated protein (MAP) kinase activation, LPA-stimulated H(2)O(2) release was independent of the tyrosine kinase activity of the epidermal growth factor (EGF) receptor. Calcium chelators, phospholipase A(2) inhibitors, and lipoxygenase inhibitors effectively blocked LPA-stimulated H(2)O(2) release, whereas cyclooxygenase inhibitors were without effect. Addition of 5-lipoxygenase products 5-hydroperoxyeicosatetraenoic acid (5-HPETE) and leukotriene B(4), but not 5-hydroxyeicosatetraenoic acid (5-HETE) and leukotriene C(4), restored LPA-stimulated H(2)O(2) release in cells treated with the lipoxygenase inhibitors nordihydroguaiaretic acid and Zileuton. These results suggest that the lipoxygenase products 5-HPETE and leukotriene B(4) are required for LPA-stimulated H(2)O(2) release in HaCaT cells.
