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

Regions of transcription initiation and termination in kinetoplastid protists lack known eukaryotic promoter and terminator elements, although epigenetic marks such as histone variants and the modified DNA base J have been localized to these regions in Trypanosoma brucei, Trypanosoma cruzi, and/or Leishmania major. Phenotypes of base J mutants vary significantly across trypanosomatids, implying divergence in the epigenetic networks governing transcription during evolution. Here, we demonstrate that the histone variants H2A.Z and H2B.V are essential in L. major using a powerful quantitative plasmid segregation-based test. In contrast, H3.V is not essential for viability or normal growth in Leishmania. Steady-state transcript levels and the efficiency of transcription termination at convergent strand switch regions (SSRs) in H3V-null parasites were comparable to WT parasites. Our genetic tests show a conservation of histone variant phenotypes between L. major and T. brucei, unlike the diversity of phenotypes associated with genetic manipulation of the DNA base J modification.
