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

p58, also referred to as the lamin B receptor, is an intrinsic protein of the inner nuclear membrane that binds in vitro to lamin B. Previous studies have demonstrated that p58 is phosphorylated in vivo and removal of its phosphate moieties affects lamin B binding. Using affinity-purified antipeptide antibodies, we have now immunoisolated p58 from bird erythrocyte lysates under isotonic, non-denaturing conditions. Analysis of the immunopurified material shows that five distinct proteins are tightly and specifically associated with p58. Two of these polypeptides can be identified as nuclear lamins A and B. The immunoisolate also contains a kinase activity that phosphorylates p58 in vivo and in vitro, exclusively at serine residues, as indicated by phosphoamino acid analysis and two-dimensional phosphopeptide mapping. Cell fractionation experiments and in vitro phosphorylation assays demonstrate that the p58 kinase resides in the nuclear envelope and is distinct from protein kinase A and cdc2 kinase, for both of which p58 is an in vitro substrate. These data suggest that p58 is interacting in vivo with a p58 kinase and the nuclear lamins.
