Effect of polyclonal immunoglobulins on neutrophil phagocytic capacity and reactive oxygen production in patients with gram-negative septicemia.
Article in Infection. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 effect of immunoglobulin (Ig) preparations on neutrophil phagocytic ability and oxidative burst in response to Escherichia coli stimulation was analyzed in 14 patients with gram-negative septicemia by an ex vivo whole blood assay using flow cytometry. In patients, neutrophils exhibited a decreased capacity to phagocytize E. coli and generate reactive oxygen products compared to healthy controls (median -68%, P < 0.01). The addition of both 7S-Ig and 19S-Ig enriched preparations in vitro resulted in a dose-dependent increase in neutrophil reactive oxygen production at concentrations of 10 g/l (median +153% and +211%, P < 0.01, respectively) and 20 g/l (median +205% and +282%, P < 0.01, respectively). A decreased neutrophil phagocytic ability was seen in patients with septicemia (median -58%) compared to healthy controls (P < 0.01). Again, the addition of 7S and 19S-Igs enhanced the phagocytic ability in a dose-dependent manner (10 g/l: median +56 and +126%; 20 g/l: median +126% and +165%, P < 0.01 for all). It can be concluded that both polyclonal Igs can increase depressed neutrophil reactive oxygen production and neutrophil phagocytosis in patients with gram-negative septicemia.
