Fluorine-18 Radiolabeled Single-Chain Antibody Variable Fragment 1F4 Targets α1-Subunit Gamma-Aminobutyric Acid Type A Receptors in Mice.

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
Gamma-aminobutyric acid type A (GABA-A) receptors are the principal inhibitory neurotransmitter receptors in the central nervous system (CNS), but their functions in the peripheral nervous system (PNS) and organs such as the heart remain poorly understood. These receptors comprise various subtypes based on subunit composition with differential brain and heart expression linked to distinct pathologies. Current positron emission tomography (PET) imaging protocols use radioligands lacking subtype specificity. To address this, we developed a PET tracer targeting the α1 subunit. The α1-specific single-chain variable fragment (scFv) 1F4 was engineered from the variable domains of monoclonal antibody (mAb) 1F4. It was efficiently
