1 · What the graph read from it

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.

2 · The registry

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 tail of the enzyme RNA polymerase II is responsible for integrating the diverse events of gene expression in eukaryotes and is indispensable for life in yeast, fruit flies, and mice. The tail features a C-terminal domain (CTD), which is comprised of tandemly repeated Y(1)-S(2)-P(3)-T(4)-S(5)-P(6)-S(7) amino acid heptads that are highly conserved across evolutionary lineages, with all mammalian polymerases featuring 52 identical heptad repeats. However, the composition and function of protozoan CTDs remain less well understood. We find that malaria parasites (genus Plasmodium) display an unprecedented plasticity within the length and composition of their CTDs. The CTD in malaria parasites which infect human and nonhuman primates has expanded compared to closely related species that infect rodents or birds. In addition, this variability extends to different isolates within a single species, such as isolates of the human malaria parasite, Plasmodium falciparum. Our results indicate that expanded CTD heptads in malaria parasites correlates with parasitism of primates and provide the first demonstration of polymorphism of the RNA polymerase II CTD within a single species. The expanded set of CTD heptads feature lysine in the seventh position (Y(1)-S(2)-P(3)-T(4)-S(5)-P(6)-K(7)), a sequence only seen otherwise in the distal portion of mammalian polymerases. These observations raise new questions for the radiation of malaria parasites into diverse hosts and for the molecular evolution of RNA polymerase II.
