Transient currents in the glycine cotransporter GlyT1 reveal different steps in transport mechanism.

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
The relation between presteady-state (transient) currents elicited by voltage steps in the absence of organic substrate and transport-associated currents in the presence of glycine was investigated in Xenopus oocytes expressing the neuronal glycine transporter GlyT1b. Saturating amounts of glycine converted the transient currents in steady transport currents. Analysis of the transient currents abolished by the substrate confirmed the intramembrane nature of the underlying charge movement process. The sigmoidal Q/V relationship had a moderate slope consistent with the known GlyT1b stoichiometry. The transient currents were best fitted by the sum of two exponentials, with the slow time constant (tau (slow)) being in the order of tens of milliseconds. The apparent affinity for glycine was in the micromolar range and voltage-dependent, slightly decreasing at positive potentials. Numerical simulations show that a simplified, three-state model is sufficient to explain the main features of GlyT1b operation.
