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 purpose of this study was to test a cloned amber-suppressing tRNA(Ser) gene derived from Drosophila melanogaster for its ability to produce amber suppression in the nematode Caenorhabditis elegans. To date, all characterized nonsense suppressors in C. elegans have been derived from tRNA(Trp) genes. Suppression was assayed by monitoring the reversal of a mutant tra-3 phenotype among individuals transformed with the cloned Drosophila suppressor gene. An amber allele of tra-3 results in masculinization of XX animals with accompanying sterility. Complete suppression was observed among the transformants. The presence of the heterologous transgene, in both suppressed experimental animals and controls injected with a non-suppressing wild-type Drosophila tRNA(Ser) gene, was verified by PCR amplification of DNA from single worms using primers flanking the tRNA(Ser) gene. Suppression by the heterologous transgene was comparable in quality to that produced by endogenous C. elegans suppressors, and, in frequency as well as quality, to that produced by a transgenic C. elegans tRNA(Trp)-derived suppressors. Thus, a heterologous suppressor gene will function in C. elegans, and it need not be based on tRNA(Trp).
