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 Distributed Charge Compton Source (DCCS) developed by Lumitron Technologies, Inc. has produced a 25-MeV electron beam with 1.7-nC macrobunches at a 100-Hz repetition rate from a compact, high-gradient X-band (11.424 GHz) accelerator. The DCCS is currently being commissioned to produce 100-MeV-class electrons, well within the very high energy electron (VHEE) energy regime, with macrobunch charges of up to 25 nC at repetition rates up to 400 Hz. The DCCS is also designed to produce imaging X rays through Laser Compton scattering. This work aims to describe the preparations for the first dosimetry experimental campaign using this accelerator system at energies ranging from 25 MeV to 90 MeV through hardware development and Monte Carlo (TOPAS) simulation studies. A significant goal of these preparations is to configure the machine so that it can be used to both image with X rays and subsequently treat with VHEEs without movement of the animal model under study. At ultra-high dose rates, this X-ray image-guided electron source could be used to investigate dose-rate dependent differential sparing of normal and malignant biological tissue, known as the FLASH effect. An indium-tin-oxide-coated, 100-μm-thick diamond window was obtained and installed in a custom flange assembly to act as the electron/X-ray vacuum exit window. Simulations at 25 MeV suggest that a scattering foil and collimator can shape the output of the accelerator to produce a 12-mm-diameter, flat-field, circular beam with a 1.7-nC macrobunch charge. This corresponds to an entrance dose of 10 Gy in less than 100 ms. These initial results highly motivate an experimental campaign toward investigating VHEE FLASH using the DCCS at Lumitron Technologies, Inc.
