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 natural vibrational frequencies of biological particles such as viruses and bacteria encode critical information about their mechanical and biological states as they interact with their local environment and undergo structural evolution. However, detecting and tracking these vibrations within a biological context at the single particle level has remained elusive. In this study, we track the vibrational motions of single, unlabeled virus particles under ambient conditions using ultrafast spectroscopy. The ultrasonic spectrum of an 80 to 100 nm lentiviral pseudovirus reveals vibrational modes in the 19 to 21 GHz range sensitive to virus morphology and 2 to 10 GHz modes with nanosecond dephasing times reflecting viral envelope protein interactions. By tracking virus trajectories over minutes, we observe acoustic mode coupling mediated by the local environment. Single particle tracking allows the capture of viral disassembly through correlated mode softening and dephasing. The sensitivity, high resolution, and speed of this approach promise deeper insights into biological dynamics and early-stage diagnostics at the single microorganism level.
