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 examined the mechanism of surface phagocytosis of Staphylococcus aureus by human polymorphonuclear leucocytes (PMN). Surface phagocytosis of unopsonized bacteria occurred, but was significantly enhanced by the presence of serum. The serum requirement was low, and a maximal effect occurred with serum concentrations of 0.25-0.5%. The opsonic effect of serum was not removed by heat inactivation of complement but was adsorbed, at low serum concentrations, by protein A, indicating that opsonin-dependent surface phagocytosis requires IgG but not C3. The requirement of opsonin-dependent surface phagocytosis for IgG was demonstrated further with purified IgG preparations as the sole opsonin. Activation of PMN by N-formyl-methionyl-leucyl-phenylalanine (FMLP) or phorbol myristate acetate (PMA) increased opsonin-independent surface phagocytosis by 47% and 66%, respectively, but had no effect on opsonin-dependent surface phagocytosis. Blockade of the PMN iC3b receptor (CR3), which has lectin-like properties, by a panel of monoclonal antibodies against the alpha- and beta-chains of CR3 did not inhibit the surface phagocytosis of opsonized or unopsonized S. aureus, and one antibody (NIMP-R10) enhanced opsonin-independent surface phagocytosis. These results indicate that the mechanism of surface phagocytosis is quite different to that observed in suspension assays. Opsonin-independent surface phagocytosis occurs and is enhanced by PMN activation, opsonin-dependent surface phagocytosis is dependent on IgG and not complement, and neither opsonin-independent nor -dependent surface phagocytosis proceeds through CR3.
