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

To determine how norepinephrine affects the basic physiological properties of catecholaminergic neurons, brain slices containing the substantia nigra pars compacta and locus coeruleus were studied with cell-attached and whole-cell recordings in control and dopamine beta-hydroxylase knockout (Dbh -/-) mice that lack norepinephrine. In the cell-attached configuration, the spontaneous firing rate and pattern of locus coeruleus neurons recorded from Dbh -/- mice were the same as the firing rate and pattern recorded from heterozygous littermates (Dbh +/-). During whole-cell recordings, synaptic stimulation produced an alpha-2 receptor-mediated outward current in the locus coeruleus of control mice that was absent in Dbh -/- mice. Normal alpha-2 mediated outward currents were restored in Dbh -/- slices after pre-incubation with norepinephrine. Locus coeruleus neurons also displayed similar changes in holding current in response to bath application of norepinephrine, UK 14304, and methionine-enkephalin. Dopamine neurons recorded in the substantia nigra pars compacta similarly showed no differences between slices harvested from Dbh -/- and control mice. These results indicate that endogenous norepinephrine is not necessary for the expression of catecholaminergic neuron firing properties or responses to direct agonists, but is necessary for auto-inhibition mediated by indirect alpha-2 receptor stimulation.
