The nucleotide sequence of five ribosomal protein genes from the cyanelles of Cyanophora paradoxa: implications concerning the phylogenetic relationship between cyanelles and chloroplasts.

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 nucleotide sequences of the ribosomal protein genes rps18, rps19, rpl2, rpl33, and partial sequence of rpl22 from cyanelles, the photosynthetic organelles of the protist Cyanophora paradoxa, have been determined. These genes form two clusters oriented in opposite and divergent directions. One cluster contains the rpl33 and rps18 genes; the other contains the rpl2, rps19, and rpl22 genes, in that order. Phylogenetic trees were constructed from both the DNA sequences and the deduced protein sequences of cyanelles, Euglena gracilis and land plant chloroplasts, and Escherichia coli, using parsimony or maximum likelihood methods. In addition, a phylogenetic tree was built from a distance matrix comparing the number of nucleotide substitutions per site. The phylogeny inferred from all these methods suggests that cyanelles fall within the chloroplast line of evolution and that the evolutionary distances between cyanelles and land plant chloroplasts are shorter than between E. gracilis chloroplasts and land plant chloroplasts.
