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
Anxiety disorders are among the most common psychiatric disorders, and understanding the underlying neurocircuitry of anxiety- and stress-related behaviors may be important for treatment. The bed nucleus of the stria terminalis (BNST) has been studied for its role in many stress-related pathologies, such as anxiety, pain, depression, and addiction. Our prior work has demonstrated that pituitary adenylate cyclase-activating polypeptide (PACAP) receptor activation in the BNST mediates many of the behavioral consequences of chronic stress. While the BNST contains local PACAP-expressing neurons, a major source of afferent PACAP is the lateral parabrachial nucleus (LPBn), and excitotoxic lesions of the LPBn substantially decreasess PACAP immunostaining in the BNST. Here, we first assessed Cre-dependent reporter expression by injecting AAV2-hSyn-DIO-mCherry into the LPBn of PACAP-IRES-Cre mice for circuit mapping studies and identified PACAP projections to the BNST, lateral capsular central nucleus of the amygdala (CeLC), and ventromedial hypothalamus (VMH). In a second study, we assessed the effects of chemogenetically activating LPBn PACAP afferents in the BNST by injecting AAV2-hSyn-DIO-hM3D(Gq)-mCherry into the LPBn of PACAP-IRES-Cre mice for Cre-dependent expression of excitatory designer receptors exclusively activated by designer drugs (DREADDs). Before behavioral testing, clozapine-N-oxide (CNO), the selective agonist of our DREADD, was infused directly into the BNST. We found that after specific activation of LPBn PACAP afferents in the BNST, mice had increased anxiety-like behavior compared with controls, while total locomotor activity was unaffected. These results indicate that activation of PACAPergic LPBn projections to the BNST may play an important role in producing anxiety-like behavior.
