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 have characterized the association of the intermediate filament protein, vimentin, with the plasma membrane, using radioiodinated lens vimentin and various preparations of human erythrocyte membrane vesicles. Inside-out membrane vesicles (IOVs), depleted of spectrin and actin, bind I125-vimentin in a saturable manner unlike resealed, right-side-out membranes which bind negligible amounts of vimentin in an unsaturable fashion. The binding of vimentin to IOVs is abolished by trypsin or acid treatment of the vesicles. Extraction of protein 4.1 or reconstitution of the membranes with purified spectrin do not basically affect the association. However, removal of ankyrin (band 2.1) significantly lowers the binding. Upon reconstitution of depleted vesicles with purified ankyrin, the vimentin binding function is restored. If ankyrin is added in excess the binding of vimentin to IOVs is quantitatively inhibited, whereas protein 4.1, the cytoplasmic fragment of band 3, band 6, band 4.5 (catalase), or bovine serum albumin do not influence it. Preincubation of the IOVs with a polyclonal anti-ankyrin antibody blocks 90% of the binding. Preimmune sera and antibodies against spectrin, protein 4.1, glycophorin A, and band 3 exhibit no effect. On the basis of these data, we propose that vimentin is able to associate specifically with the erythrocyte membrane skeleton and that ankyrin constitutes its major attachment site.
