On the Function of Trans-Splicing: No Evidence for Widespread Proteome Diversification in Trypanosomes.
Article in Genome biology and evolution, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
A long-standing mystery of genomic/transcriptomic structure involves spliced leader trans-splicing (SLTS), in which short RNA "tags" transcribed from a distinct genomic locus is added near the 5' end of RNA transcripts by the spliceosome. SLTS has been observed in diverse eukaryotes in a phylogenetic pattern implying recurrent independent evolution. This striking convergence suggests important functions for SLTS, however no general novel function is known. Recent findings of frequent alternative SLTS (ALT-TS) suggest that ALT-TS could impart widespread functionality. Here, we tested the hypothesis that ALT-TS diversifies proteomes by comparing splicing patterns in orthologous genes between two deeply diverged trypanosome parasites. We also tested proteome diversification functions of ALT-TS by utilizing ribosome profiling sequence data. Finally, we investigated ALT-TS as a mechanism to regulate the expression of unproductive transcripts. Although our results indicate the functional importance of some cases of trans-splicing, we find no evidence for the hypothesis that proteome diversification is a general function of trans-splicing.
