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

Postmortem studies in schizophrenia patients have demonstrated robust alterations in GABAergic markers throughout the neuraxis. It has been suggested that these alterations are restricted to subpopulations of interneurons, such as those containing the calcium binding protein parvalbumin. Indeed, a reduction in parvalbumin expression is a consistent observation in human postmortem studies, as well as, in a wide and diverse variety of animal models. However, it still remains to be determined whether this decrease in parvalbumin expression contributes to, or is a consequence of the disease. Here we utilize lentiviral delivered shRNA and demonstrate that a selective reduction in parvalbumin mRNA expression induces hyperactivity within the ventral hippocampus. In addition, we observe downstream increases in dopamine neuron population activity without changes in average firing rate or percent burst firing. These changes in dopamine neuron activity were associated with an enhanced locomotor response to amphetamine administration. These data therefore demonstrate that a reduction in ventral hippocampal parvalbumin expression is sufficient, in and of itself, to induce an augmented dopamine system function and behavioral hyper-responsivity to amphetamine, implicating a potential key role for parvalbumin in the pathophysiology of schizophrenia.
