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 chloroplast genome evolves through the course of evolution. Various types of mutational events are found within the chloroplast genome, including insertions-deletions (InDels), substitutions, inversions, gene rearrangement, and pseudogenization of genes. The pseudogenization of the chloroplast threonine (trnT-GGU) gene was previously reported in Cryptomeria japonica (Cupressaceae), Pelargonium × hortorum (Geraniaceae), and Anaphalis sinica and Leontopodium leiolepis of the tribe Gnaphalieae (Asteroideae, Asteraceae). Here, we performed a broad analysis of the trnT-GGU gene among the species of 13 subfamilies of Asteraceae and found this gene as a pseudogene in core Asteraceae (Gymnarrhenoideae, Cichorioideae, Corymbioideae, and Asteroideae), which was linked to an insertion event within the 5' acceptor stem and is not associated with ecological factors such as habit, habitat, and geographical distribution of the species. The pseudogenization of trnT-GGU was not predicted in codon usage, indicating that the superwobbling phenomenon occurs in core Asteraceae in which a single transfer RNA (trnT-UGU) decodes all four codons of threonine. To the best of our knowledge, this is the first evidence of a complete clade of a plant species using the superwobbling phenomenon for translation.
