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

Here, we present a protocol to equalize antibody concentrations between samples to focus analysis on IgG properties rather than phagocytosis driven by antibody concentration. We describe steps for quantitating antigen-specific IgG in serum using a suitable binding assay, diluting samples to equalize IgG concentration, and using the antibody-dependent cellular phagocytosis (ADCP) assay. We then detail procedures for measuring differences in antibody properties between experimental groups by running diluted samples in the ADCP assay or other effector function assays. For complete details on the use and execution of this protocol, please refer to St. Germain et al.
