1 · What the graph read from it

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.

2 · The registry

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

Protamine P1 genes have been sequenced by PCR amplification and direct DNA sequencing from 9 primates representing 5 major families, Cebidae (new world monkeys), Cercopithecidae (old world monkeys), Hylobatidae (gibbons), Pongidae (gorilla, orangutan, and chimpanzee), and Hominidae (human). In this recently diverged group of primates these genes are clearly orthologous but very variable, both at the DNA level and in their expressed amino acid sequences. The rate of variation amongst the protamine P1s indicates that they are amongst the most rapidly diverging polypeptides studied. However, some regions are conserved both in primates and generally in other placental mammals. These are the 13 N-terminal residues (including a region of alternating serine and arginine residues (the motif SRSR, res. 10-13) susceptible to Ser phosphorylation), a tract of six Arg residues (res. 24-29) in the center of the molecule, and a six-residue region (RCCRRR, res. 39-44), consisting of a pair of cysteines flanked by arginines. Detailed consideration of nearest-neighbor matrices and trees based on maximum parsimony indicates that P1 genes from humans, gorillas, and chimpanzees are very similar. The amino acid and nucleotide differences between humans and gorillas are fewer than those between humans and chimpanzees. This finding is at variance with data from DNA-DNA hybridization and extensive globin and mitochondrial DNA sequences which place human and chimpanzee as closest relatives in the super family, Hominoidea. This may be related to the fact that protamine P1s are expressed in germ line rather than somatic cells.(ABSTRACT TRUNCATED AT 250 WORDS)
