Astronaut dose coefficients calculated using GEANT4 and comparison with ICRP123.

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
Fluence-to-dose conversion coefficients are fundamental ingredients to calculate astronaut radiation dose in space. For this purpose, the conversion coefficients for isotropic radiation provided by the International Commission on Radiological Protection in Publication 123 (ICRP123) are widely used. Understanding the uncertainties in these coefficients is important for a precise calculation of radiation dose. In this work, we present a systematic study of unshielded dose coefficients calculated by means of the GEANT4 Monte Carlo simulation toolkit and the human voxel phantoms defined in ICRP Publication 110. Four GEANT4 physics lists, featured with two variations of electromagnetic and two variations of hadronic interaction models, were used in the study. Absorbed dose and dose equivalent coefficients with both the ICRP60 and NASA quality factors were calculated, for individual cosmic nuclei with charge from Z
