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

Norepinephrine is a key neuromodulator of hypothalamic circuits that regulate energy balance. Previous studies suggested that norepinephrine inhibits proopiomelanocortin (POMC) neurons of the arcuate nucleus via α2a-adrenoceptors (ADRA2A), but the underlying mechanisms and physiological relevance of this pathway were not assessed. We therefore investigated how ADRA2 activation regulates POMC neuron activity and whether Adra2a expressed in POMC neurons contributes to energy and glucose homeostasis in vivo. We used whole-cell patch clamp electrophysiology in male and female mice to evaluate the impact of norepinephrine and the ADRA2 agonist UK 14,304 on definitive POMC neurons in the arcuate nucleus. We also generated and validated a novel Adra2a-flox mouse line, which was crossed with Pomc-CreERT2 mice to produce inducible POMC-specific Adra2a knockout mice (POMC
