The nicotinic α5 subunit can replace either an acetylcholine-binding or nonbinding subunit in the α4β2* neuronal nicotinic receptor.

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.
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
Heteropentameric neuronal nicotinic receptors assemble so that the canonical acetylcholine-binding sites are located at the interfaces between two pairs of subunits, while the fifth subunit does not participate in a canonical transmitter-binding site. Several subunits are considered to be unable to participate in forming a functional receptor when they occupy a position that would contribute to such a site, including the α5 subunit. The α5 subunit is of interest because of its apparent involvement in nicotine dependence and in the control of dopamine release. We have examined this question using α4 and β2 subunits in concatemeric constructs with the α5 subunit, expressed in Xenopus oocytes. Using dimeric constructs of α4 and β2 subunits expressed with free α5 and pentameric constructs incorporating a single copy of α5, we find that the α5 subunit can occupy the position of a nonbinding subunit, or replace a β2 subunit participating in a canonical binding site. The resulting receptors functionally resemble pentamers assembled with two copies of α4 and three copies of β2. Functional receptors apparently cannot be formed with α5 subunits in both canonical binding sites. These observations extend the present ideas on the possible positions in the pentamer that may be occupied by the α5 subunit, and suggest that additional physiologic or pharmacological subtypes of neuronal nicotinic receptors may be present in neurons.
