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 Desulfurococcus mobilis genes fus (encoding EF-2) and tuf (for EF-1 alpha) were cloned and sequenced together with genes for ribosomal proteins S10 (rps10) and S7 (rps7). Unlike Methanococcus, which displays the bacterial-like fus and tuf gene context 5'-rps12-rps7-fus-tuf-3', and similar to Sulfolobus and Pyrococcus, the Desulfurococcus fus gene (734 codons) has a distinct chromosomal location. Moreover, tuf (441 codons) is the promoter-proximal unit of a three-gene cluster comprising the genes rps10 (98 codons) and tRNA(Ser); the arrangement of the cluster is 5'-tuf-91 bp spacer -rps10-138 bp spacer -tRNA(Ser)-3' and the tuf gene is preceded by a canonical archaeal promoter. The D. mobilis gene rps7 (198 codons) is located further upstream from tuf (535 bp 'silent' intergenic spacing) and no rps12 homolog occurs in its immediate vicinity. Also, judging from putative promoter and transcription termination sequences, rps7 appears to be separately transcribed. Analysis of the predicted fus and tuf gene products revealed the three consensus motifs characteristic of GTP-binding proteins, and the fus-encoded EF-2 protein also displayed the consensus sequence required for ADP-ribosylation by Diphtheria toxin. Both EF sequences were definitely crenarchaeal by comparison with available homologs from other Archaea. Outgroup-rooted phylogenies derived from the sequences of ribosomal proteins S10 and S7 yielded the Sulfolobus-Desulfurococcus association at a high bootstrap confidence level.
