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

Adamantane derivative IEM-1676 (Ad-N(+)H(2)-(CH(2))(5)-N(+)Me(3)) causes open-channel block of Ca(2+)-permeable AMPA receptors when applied externally, but internal application results in both closed- and open-channel block. The relationships between blocking action of externally and internally applied IEM-1676 were studied using patch clamp technique. Extracellular action of IEM-1676 was decreased by its intracellular application, thus suggesting that the binding sites of the externally and internally applied drug coincide or at least overlap significantly. We demonstrated that internal closed-channel block is voltage-dependent and occurs at the region where the externally applied drug is trapped. We conclude that the selectivity filter of the closed AMPA receptor channel is not occluded and remains permeable for organic cations.
