An in vitro characterisation of the Trichomonas vaginalis TATA box-binding proteins (TBPs).

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 protozoan parasite Trichomonas vaginalis is a common human pathogen from one of the earliest-diverging eukaryotic lineages. At the transcriptional level, the highly conserved Inr element of RNA pol II-transcribed genes surrounds the transcription start site and is recognised by IBP39, a protein exclusive of T. vaginalis. Typical TATA boxes have not been identified in this organism but, in contrast, BLAST analyses of the T. vaginalis genome identified two genes encoding putative TATA-binding proteins (herein referred to as TvTBP1 and TvTBP2). The goal of this work was to characterise these two proteins at the molecular level. Our results show that both TvTBPs theoretically adopt the saddle-shaped structure distinctive to TBPs and both Tvtbp genes are expressed in T. vaginalis. TvTBP1 did not complement a Saccharomyces cerevisiae mutant lacking TBP; however, TvTBP1 and TvTBP2 proteins bound T. vaginalis DNA promoter sequences in EMSA assays. We propose that TvTBP1 may be part of the preinitiation transcription complex in T. vaginalis since TvTBP1 recombinant protein was able to bind IBP39 in vitro. This work represents the first approach towards the characterisation of general transcription factors in this early divergent organism.
