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 tRNA(His) guanylyltransferase (Thg1) family comprises a set of unique 3'-5' nucleotide addition enzymes found ubiquitously in Eukaryotes, where they function in the critical G(-1) addition reaction required for tRNA(His) maturation. However, in most Bacteria and Archaea, G(-1) is genomically encoded; thus post-transcriptional addition of G(-1) to tRNA(His) is not necessarily required. The presence of highly conserved Thg1-like proteins (TLPs) in more than 40 bacteria and archaea therefore suggests unappreciated roles for TLP-catalyzed 3'-5' nucleotide addition. Here, we report that TLPs from Bacillus thuringiensis (BtTLP) and Methanosarcina acetivorans (MaTLP) display biochemical properties consistent with a prominent role in tRNA 5'-end repair. Unlike yeast Thg1, BtTLP strongly prefers addition of missing N(+1) nucleotides to 5'-truncated tRNAs over analogous additions to full-length tRNA (k(cat)/K(M) enhanced 5-160-fold). Moreover, unlike for -1 addition, BtTLP-catalyzed additions to truncated tRNAs are not biased toward addition of G, and occur with tRNAs other than tRNA(His). Based on these distinct biochemical properties, we propose that rather than functioning solely in tRNA(His) maturation, bacterial and archaeal TLPs are well-suited to participate in tRNA quality control pathways. These data support more widespread roles for 3'-5' nucleotide addition reactions in biology than previously expected.
