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 acquisition and retrieval of contextual fear memory requires coordinated neural activity in the hippocampus, medial prefrontal cortex (mPFC), and amygdala. The contextual information encoded in the hippocampus is conveyed to the mPFC and amygdala for contextual fear conditioning. Previous studies have suggested that a CA1 neuronal population in the ventral hippocampus (VH) projects to both the mPFC and amygdala and is recruited in context-dependent control of conditioned fear. However, how double-projecting ventral CA1 hippocampal (vCA1) neurons modulate the activity of the mPFC and amygdala at the synaptic level has not been determined previously. Here, we show that the optogenetic silencing of the VH prevented the recall of contextual fear memory in mice, indicating its role in contextual fear expression. In dual retrograde viral tracing and c-Fos immunostaining experiments, we found that a proportion of vCA1 neurons projected to both the mPFC and amygdala and were recruited preferentially during context exposure, suggesting their role in encoding context representations. Moreover, optogenetic stimulation of axon collaterals of double-projecting vCA1 neurons induced monosynaptic excitatory responses in both the mPFC and basal amygdala, indicating that they could convey contextual information through the VH-mPFC and VH-amygdala pathways. The activation of double-projecting vCA1 neurons also induced action potential firings in the mPFC neurons that project to the amygdala, suggesting that they can also activate the VH-mPFC-amygdala pathway. With these synaptic mechanisms, double-projecting vCA1 neurons could induce synchronized neural activity in the mPFC and amygdala and convey contextual information efficiently to the basal amygdala for contextual fear conditioning.
