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
Post-transcriptional modification of the tRNA anticodon loop is critical for translation. Yeast Trm7 is required for 2'-O-methylation of C(32) and N(34) of tRNA(Phe), tRNA(Trp), and tRNA(Leu(UAA)) to form Cm(32) and Nm(34), and trm7-Δ mutants have severe growth and translation defects, but the reasons for these defects are not known. We show here that overproduction of tRNA(Phe) suppresses the growth defect of trm7-Δ mutants, suggesting that the crucial biological role of Trm7 is the modification of tRNA(Phe). We also provide in vivo and in vitro evidence that Trm7 interacts with ORF YMR259c (now named Trm732) for 2'-O-methylation of C(32), and with Rtt10 (named Trm734) for 2'-O-methylation of N(34) of substrate tRNAs and provide evidence for a complex circuitry of anticodon loop modification of tRNA(Phe), in which formation of Cm(32) and Gm(34) drives modification of m(1)G(37) (1-methylguanosine) to yW (wyebutosine). Further genetic analysis shows that the slow growth of trm7-Δ mutants is due to the lack of both Cm(32) and Nm(34), and the accompanying loss of yW, because trm732-Δ trm734-Δ mutants phenocopy trm7-Δ mutants, whereas each single mutant is healthy; nonetheless, TRM732 and TRM734 each have distinct roles, since mutations in these genes have different genetic interactions with trm1-Δ mutants, which lack m(2,2)G(26) in their tRNAs. We speculate that 2'-O-methylation of the anticodon loop may be important throughout eukaryotes because of the widespread conservation of Trm7, Trm732, and Trm734 proteins, and the corresponding modifications, and because the putative human TRM7 ortholog FTSJ1 is implicated in nonsyndromic X-linked mental retardation.
