Biodistribution of PET radiotracers in tumor-bearing TRAMP mice administered by retroorbital or jugular vein injections.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Nuclear medicine is an important tool for use in molecular imaging of important biological processes. Methods for intravenous delivery of radiotracers remains a challenge, with tail vein injections demonstrated to be technically difficult and lacking in reproducibility. Other intravenous methods include jugular vein (JV) injection, which requires a more invasive and precise microsurgical technique. Although the retroorbital (RO) sinus drains directly into the JV, and RO injections are minimally invasive and simpler to perform, they remain underutilized, perhaps due to a lack of studies demonstrating their performance. This study provides a comprehensive comparison of dynamic tissue biodistribution of three categories of commonly utilized radiopharmaceuticals between JV and RO injection methods in prostate tumor-bearing mice using PET-CT imaging. Results show that JV and RO injections have equivalent dynamic tissue biodistributions across the three categories of radiopharmaceuticals used: (1) small molecule measuring tumor metabolism (
