Low concentrations of ethanol during irradiation drastically reduce DNA damage caused by very high doses of ionizing radiation.

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
Presence of low concentrations (1-2%) of ethanol during irradiation exhibited significant protection against DNA damage caused by very high doses (2-12 kGy) of 60 Co-gamma-rays in vitro. Radiation-induced DNA damage was substantially reduced in different types of DNA molecules (chromosomal DNA from Anabaena 7120 or Deinococcus radiodurans or bacteriophage Lambda, and plasmid pBluescript DNA) when irradiated in the presence of ethanol, thus indicating the generic nature of ethanol protection. The radioprotection appeared to be a consequence of the well known ability of ethanol to scavenge hydroxyl radicals. Addition of ethanol during 6 kGy irradiation also reduced DNA damage in vivo and improved post-irradiation growth recovery of Anabaena 7120 cultures. To our knowledge, this is the first instance of ability of very low ethanol concentrations to protect DNA from damage triggered by extremely high doses of 60 Co-gamma rays.
