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
Organisms must have efficient mechanisms of DNA repair and recombination to prevent alterations in their genetic information due to DNA damage. There is evidence for DNA repair and recombination in plastids of higher plants, although very little is known at the biochemical level. Many chloroplast proteins are of eubacterial ancestry, suggesting that the same could be true for the components of a DNA repair and recombination system. A 39-kD protein, immunologically related to Escherichia coli RecA, is present in chloroplasts of pea (Pisum sativum L.). Bandshift gel assays suggest that it binds single-stranded DNA. Its steady-state level is increased by several DNA-damaging agents. These results are consistent with it being a plastid homolog of E. coli RecA protein, presumably involved in DNA repair and recombination, and with the existence of an SOS-like response in pea leaf cells. Experiments with protein synthesis inhibitors suggest that the 39-kD chloroplast protein is encoded in the nucleus.
