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
Purpose: The aim of this paper was to present the measured photon fluence spectra emitted by the electronic brachytherapy (eBT) unit Papillon 50. Material and methods: Spectra were collected with a compact CdTe spectrometer in air at a distance of 52 cm from the unit output window, for three different applicators attached to the unit and at several angles with respect to the beam axis. Results: The fluence spectra recorded for this device showed lower energy of the photon spectrum end-point than anticipated. The end-point energy was found to be (47.6 ±0.2) keV for the nominal high voltage bias of 50 kV set by the operator. Full-energy peaks in the spectra identified characteristic photons emitted by the rhenium anode, and by molybdenum and silver supposedly present in the inner coating of the applicators. An asymmetry in the half-value layer values of measured spectra was observed. Conclusions: The presented work provides a comprehensive dataset of photon fluence spectra for traceable dosimetry using the Papillon 50 eBT device, which is required, for example, for correcting the energy dependence of detectors or as an input for Monte Carlo calculations. Spectrometry and dose characterization studies are needed for eBT systems.
