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

1. The effect has been examined of the accessory alpha2-delta and beta subunits on the properties of alpha1G currents expressed in monkey COS-7 cells and Xenopus oocytes. 2. In immunocytochemical experiments, the co-expression of alpha2-delta increased plasma membrane localization of expressed alpha1G and conversely, the heterologous expression of alpha1G increased immunostaining for endogenous alpha2-delta, suggesting an interaction between the two subunits. 3. Heterologous expression of alpha2-delta together with alpha1G in COS-7 cells increased the amplitude of expressed alpha1G currents by about 2-fold. This finding was confirmed in the Xenopus oocyte expression system. The truncated delta construct did not increase alpha1G current amplitude, or increase its plasma membrane expression. This indicates that it is the exofacial alpha2 domain that is involved in the enhancement by alpha2-delta. 4. Beta1b also produced an increase of functional expression of alpha1G, either in the absence or the presence of heterologously expressed alpha2-delta, whereas the other beta subunits had much smaller effects. 5. None of the accessory subunits had any marked influence on the voltage dependence or kinetics of the expressed alpha1G currents. These results therefore suggest that alpha2-delta and beta1b interact with alpha1G to increase trafficking of, or stabilize, functional alpha1G channels expressed at the plasma membrane.
