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

An important function of the low affinity IgG Fc receptor FcRII-B2 (FcR) on macrophages is the internalization of soluble antigen-antibody complexes for lysosomal degradation. Most endocytic receptors possess tyrosine-containing cytoplasmic determinants required for endocytosis. In many proteins, signals which overlap with the endocytosis determinant and share the same critical tyrosine residue also mediate basolateral sorting in the trans-Golgi network of epithelial cells. Despite the presence of two tyrosine residues in the FcR cytosolic domain, neither one is absolutely required for coated pit localization or basolateral targeting. Nevertheless, a short domain of 13 residues containing one of the non-critical tyrosine residues mediates endocytosis and basolateral delivery. Alanine scan mutagenesis of this region now revealed a critical role of a leucine-leucine motif in both events. These findings suggest that endocytosis and basolateral sorting can be mediated by both tyrosine- and di-leucine-based signals and confirm the close relationship between the two determinants already observed for 'classical' tyrosine-dependent motifs.
