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

We have determined complete gene sequences encoding the largest subunit of the RNA polymerase II (RBP1) from two Microsporidia, Vairimorpha necatrix and Nosema locustae. Phylogenetic analyses of these and other RPB1 sequences strongly support the notion that Microsporidia are not early-diverging eukaryotes but instead are specifically related to Fungi. Our reexamination of elongation factors EF-1alpha and EF-2 sequence data that had previously been taken as support for an early (Archezoan) divergence of these amitochondriate protists show such support to be weak and likely caused by artifacts in phylogenetic analyses. These EF data sets are, in fact, not inconsistent with a Microsporidia + Fungi relationship. In addition, we show that none of these proteins strongly support a deep divergence of Parabasalia and Metamonada, the other amitochondriate protist groups currently thought to compose early branches. Thus, the phylogenetic placement among eukaryotes for these protist taxa is in need of further critical examination.
