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

It has previously been shown that human neutrophils generate substantial quantities of LTB4 when stimulated with the calcium ionophore, A23187, or with unopsonized zymosan. We now report that normal human neutrophils produced substantial quantities of LTB4 (measured by radioimmunoassay and validated by RP-HPLC) when incubated with large non-phagocytosable IgG-coated beads (Sepharose 4B). LTB4 was identified in both the extra and intracellular compartments. The production of LTB4 was dependent upon the number of IgG-coated particles and the concentration of IgG bound to the beads. Release was maximal after a 15-30 min incubation time and was enhanced by prior activation of the neutrophils with the synthetic bacterial product f-met-leu-phe. Comparable LTB4 production was also observed when neutrophils were incubated with antigen (Aspergillus fumigatus)-coated beads sensitized with purified IgG obtained from the sera of patients with allergic bronchopulmonary aspergillosis. These results suggest a further mechanism by which neutrophils may be activated to produce inflammatory mediators in the tissues.
