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

The electrical properties of sustentacular cells (SCs) in the olfactory epithelium (OE) were investigated in tissue slices taken from neonatal mice (P0-P4). Conventional whole-cell recordings were obtained from SCs and also from olfactory receptor neurones (ORNs) in situ. SCs had a larger apparent cell capacitance (C(cell)) (18.6 +/- 0.5 pF) than ORNs (4.4 +/- 0.4 pF) and a lower apparent membrane resistance (R(m)) (160 +/- 11 MOmega versus 664 +/- 195 MOmega, respectively). When corrected for a seal resistance of 1 GOmega, these mean R(m) values were increased to 190 MOmega and 2 GOmega in SCs and ORNs, respectively. SCs generated a TTX (1 microm)-resistant voltage-activated Na(+) current (I(Na)) that had a peak density at -38 mV of -44 pA pF(-1) and supported action potential firing. Peak current density of I(Na) in neurones was 510 +/- 96 pA pF(-1). The outward K(+) current in SCs was composed (> 70%) of a TEA (2 mm)-sensitive component that was mediated by the opening of large-conductance (237 +/- 10 pS; BK) channels. The resting leak conductance (g(L)) of SCs was permeable to monovalent cations and anions and was largely inhibited by substitution of external Na(+) with NMDG and by internal F(-) with gluconate. g(L) deactivated up to 50% at potentials negative of -70 mV and was inhibited by 18beta-glycyrrhetinic acid (20 mum). SCs were identified using fluorescent dyes (Lucifer Yellow and Alexa Fluor 488) in the whole-cell patch pipette-filling solution. Our findings indicate that SCs in the OE of neonates are electrically excitable and are distinguishable from neurones by a having a resting g(L).
