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

Several distinct components of voltage-gated sodium current have been recorded from native dorsal root ganglion (DRG) neurons that display differences in gating and pharmacology. This study compares the electrophysiological properties of two peripheral nerve sodium channels that are expressed selectively in DRG neurons (Na(v)1.7 and Na(v)1.8). Recombinant Na(v)1.7 and Na(v)1.8 sodium channels were coexpressed with the auxiliary beta(1) subunit in Xenopus oocytes. In this system coexpression of the beta(1) subunit with Na(v)1.7 and Na(v)1.8 channels results in more rapid inactivation, a shift in midpoints of steady-state activation and inactivation to more hyperpolarizing potentials, and an acceleration of recovery from inactivation. The coinjection of beta(1) subunit also significantly increases the expression of Na(v)1.8 by sixfold but has no effect on the expression of Na(v)1.7. In addition, a great percentage of Na(v)1.8+beta(1) channels is observed to enter rapidly into the slow inactivated states, in contrast to Nav1.7+beta(1) channels. Consequently, the rapid entry into slow inactivation is believed to cause a frequency-dependent reduction of Na(v)1.8+beta(1) channel amplitudes, seen during repetitive pulsing between 1 and 2 Hz. However, at higher frequencies (>20 Hz) Na(v)1.8+beta(1) channels reach a steady state to approximately 42% of total current. The presence of this steady-state sodium channel activity, coupled with the high activation threshold (V(0.5) = -3.3 mV) of Na(v)1.8+beta(1), could enable the nociceptive fibers to fire spontaneously after nerve injury.
