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

Various isomers of polychlorinated biphenyls (PCB) were studied to induce and modulate the generation of lipo-oxygenase products (leukotrienes) from human polymorphonuclear granulocytes (PMN) under non-cytotoxic conditions. Stimulation of human PMN with PCB did not induce leukotriene generation by themselves, but modulated the subsequent leukotriene formation when opsonized zymosan or sodium fluoride (NaF) were applied as stimuli. The simultaneous addition of PMN with opsonized zymosan and PCB, especially 3,3',4,4'-TCB, led to an increased generation of leukotrienes compared to the control. 3,3',4,4'-TCB exceeded the activity of the remainder PCB in a dose-dependent manner and also induced a chemiluminescence response from PMN. The simultaneous incubation of PMN with NaF and 3,3'-DCB,3,3',4,4'-TCB and 2,2',3,3'-TCB showed an inhibitory effect on leukotriene generation unlike NaF stimulation in the absence of PCB. Incubation of PMN with PCB had no significant effect on leukotriene generation induced by the Ca-ionophore (5 microM). Our data show a direct relationship between the extent of PMN stimulation and the chloro-substitution pattern of the PCB in combination with the different stimuli.
