Novel chaperonins in a prokaryote.
Article in Journal of molecular evolution, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Group II chaperonins belong to the Hsp60 family occurring in archaea and eukaryotes. The archaeal chaperonins build the thermosome, which is similar to the eukaryotic CCT (chaperonin-containing TCP-1). Eukaryotes have eight subunits, and up until now, it was thought that archaea had between one and three subunits, depending on the species. We now report two novel subunits, termed Hsp60-4 and Hsp60-5, in the archaeon Methanosarcina acetivorans, which also has Hsp60-1, Hsp60-2, and Hsp60-3 with orthologs in Methanosarcinae. Hsp60-4 and Hsp60-5 occur only in M. acetivorans, which makes this organism unique in that it has the highest number of chaperonin subunits ever described for an archaeon. Evolutionary analysis suggests that either Hsp60-4 or Hsp60-5 paralogs have arisen by gene duplication with vastly increased accepted substitution rates or that they represent ancestral types found only in this species.
