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

Return of fear is a serious problem in exposure-based treatments of anxiety disorders. Renewal of the fear response may occur when re-encountering the conditioned stimulus within a novel context. Findings in rodents underpin the hippocampus' role in conditioned fear renewal in novel contexts, but it has yet to be investigated in humans. Forty-six healthy men took part in a 2-day, context-dependent, cued fear conditioning paradigm with fear acquisition, extinction learning (day 1) and extinction recall in the acquisition, extinction and a novel context one day later. Conditioned evaluative, skin conductance responses (SCRs) and blood-oxygen-level-dependent responses served as dependent variables. Context-dependent fear renewal was reflected in stronger conditioned SCRs. In the acquisition context, individuals with a higher renewal of conditioned SCRs showed stronger activation of the fear circuit. Hippocampal activation distinguished conditioned responding in the novel compared with the extinction context. Individuals with a stronger renewal of conditioned SCRs in the novel context showed increased effective connectivity of hippocampal activation foci with structures in the fear and extinction network. These results outline the pivotal role of the hippocampus and its connectivity in conditioned fear renewal in a novel context in humans and might have important implications for exposure therapy in anxiety disorders.
