Purification and characterization of seven chloroplast ribosomal proteins: evidence that organelle ribosomal protein genes are functional and that NH2-terminal processing occurs via multiple pathways in chloroplasts.
Article in Plant molecular biology, 1992. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Putative genes for 21 ribosomal proteins (RPs) have been identified in the chloroplast DNA of four plants by nucleotide sequencing and homology comparison but few of the gene products have been characterized. Here we report the purification and N-terminal sequencing of seven proteins from the spinach chloroplast ribosome. The data show them to be the homologues of Escherichia coli RPs L20, L32, L33, L36, S12, S16 and S19, and thus support the view that their genes identified in the chloroplast DNA represent functional genes. The initiating methionine residue was not detected in the mature protein in most cases but it was present in S16, indicating that only the formyl group is removed in this case. This result and the previously reported finding of N-methyl alanine at the N-terminus of chloroplast L2 indicate the existence of multiple N-terminal processing pathways in the chloroplast.
