Phylogeny of immunoglobulin heavy chain isotypes: structure of the constant region of Ambystoma mexicanum upsilon chain deduced from cDNA sequence.
Article in Immunogenetics, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
An RNA polymerase chain reaction strategy was used to amplify and clone a cDNA segment encoding for the complete constant part of the axolotl IgY heavy (C upsilon) chain. C upsilon is 433 amino acids long and organized into four domains (C upsilon 1-C upsilon 4); each has the typical internal disulfide bond and invariant tryptophane residues. Axolotl C upsilon is most closely related to Xenopus C upsilon (40% identical amino acid residues) and C upsilon 1 shares 46.4% amino acid residues among these species. The presence of additional cysteines in C upsilon 1 and C upsilon 2 domains is consistent with an additional intradomain S-S bond similar to that suggested for Xenopus C upsilon and C chi, and for the avian C upsilon and the human C epsilon. C upsilon 4 ends with the Gly-Lys dipeptide characteristic of secreted mammalian C gamma 3, human C epsilon 4, and avian and anuran C upsilon 4, and contains the consensus [G/GT(AA)] nucleotide splice signal sequence for joining C upsilon 4 to the transmembrane region. These results are consistent with the hypothesis of an ancestral structural relationship between amphibian, avian upsilon chains, and mammalian epsilon chains. However, these molecules have different biological properties: axolotl IgY is secretory Ig, anuran and avian IgY behave like mammalian IgG, and mammalian IgE is implicated in anaphylactic reactions.
