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

We analyzed DNA-fragmentation in human polymorphonuclear neutrophil granulocytes (PMNs) from healthy donors after addition of exogenous arachidonic acid (AA) and eicosapentaenoic acid (EPA) by flow cytometry (propidium iodide staining of DNA and DNA strand break detection). The PMNs were incubated from 30 min up to 48 hours in RPMI 1640 which was supplemented with different concentrations of AA or EPA (5-40 microM). In contrast to EPA the addition of AA led to a significant increase in apoptosis up to 67.8% compared to the RPMI-control whereas the addition of EPA led to an inhibition of DNA-fragmentation. When the cells were incubated with MK 886 (1 microM, inhibitor of leukotriene biosynthesis) an increase in DNA-fragmentation (up to 63.3%) was observed. Conversely, in the presence of indomethacin (1 microM, inhibitor of prostanoid synthesis) an inhibition in DNA-fragmentation (up to 60.9%) occurred. Furthermore, preincubation of PMNs with pentoxifylline (1mM, phosphodiesterase inhibitor) reduced AA-stimulated DNA-fragmentation up to 43.4%. These data provide evidence for the involvement of AA and distinct AA metabolites in the regulation of apoptosis in human PMNs.
