Optimization and Biodistribution of [(11)C]-TKF, An Analog of Tau Protein Imaging Agent [(18)F]-THK523.

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
The quantification of neurofibrillary tangles (NFTs) using specific PET tracers can facilitate the diagnosis of Alzheimer's disease (AD) and allow monitoring of disease progression and treatment efficacy. [(18)F]-THK523 has shown high affinity and selectivity for tau pathology. However, its high retention in white matter, which makes simple visual inspection difficult, may limit its use in research or clinical settings. In this paper, we optimized the automated radiosynthesis of [(11)C]-TKF and evaluated its biodistribution and toxicity in C57 mice. [(11)C]-TKF can be made by reaction precursor with [(11)C]MeOTf or (11)CH₃I, but [(11)C]MeOTf will give us higher labeling yields and specific activity. [(11)C]-TKF presented better brain uptake in normal mouse than [(18)F]-THK523 (3.23% ± 1.25% ID·g(-1) vs. 2.62% ± 0.39% ID·g(-1) at 2 min post-injection). The acute toxicity studies of [(11)C]-TKF were unremarkable.
