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.
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
The interaction between human endothelial cells (EC) and leukocytes during inflammation is in part mediated through the release of soluble factors. Since platelet-activating factor (PAF) is a potent mediator of inflammatory responses, we investigated the potential of PAF to modulate IL-6 and GM-CSF production by EC. Exposure of these cells to PAF resulted in a concentration-dependent increase in IL-6 production, with a maximum at 10(-10) M PAF. Sequential incubation of EC with PAF and TNF alpha resulted in a synergistic increase of IL-6 production. This effect was specific for PAF since it was prevented by preincubation with the PAF receptor antagonist, WEB 2086. Northern blot analysis revealed enhanced IL-6 mRNA expression in PAF-treated EC. However, the synergy observed in protein synthesis between PAF and TNF alpha was not reflected in IL-6 mRNA accumulation, suggesting a post-translational modulation. Pretreatment of EC with the protein synthesis inhibitor cycloheximide before their exposure to PAF resulted, after washout of the cycloheximide, in a markedly augmented production of IL-6, suggesting a synergy between augmented IL-6 mRNA accumulation by PAF and IL-6 mRNA superinduction by cycloheximide. GM-CSF production by EC was also stimulated by the combined effects of PAF and TNF alpha, but PAF alone did not affect GM-CSF production. Taken together, our data suggest that PAF can stimulate EC to synthesize cytokines, including IL-6 and GM-CSF, which may contribute to local and, possibly, systemic responses during inflammation.
