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

Over-generalization of negative memory is common in psychiatric disorders, including depression and anxiety. Here, we present a protocol to dissociate memory generalization from memory strengthening and induce lasting stress-related behavioral alterations using contextual fear conditioning in adult mice. We describe the steps for repeated conditioning in identical or distinct contexts, followed by memory testing and behavioral assays of stress-related phenotypes. This protocol enables the investigation of the behavioral and biological mechanisms underlying pathological memory generalization and its consequences. For complete details on the use and execution of this protocol, please refer to Cheng et al.
