Phylogenetic comparisons suggest that distance from the locus control region guides developmental expression of primate beta-type globin genes.

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
Phylogenetic inferences drawn from comparative data on mammalian beta-globin gene clusters indicate that the ancestral primate cluster contained a locus control region (LCR) and five paralogously related beta-type globin loci (5'-LCR-epsilon-gamma-psieta-delta-beta-3'), with epsilon and gamma expressed solely during embryonic life. A gamma locus tandem duplication (5'-gamma(1)-gamma(2)-3') triggered gamma's evolution toward fetal expression but by a different trajectory in platyrrhines (New World monkeys) than in catarrhines (Old World monkeys and apes, including humans). In platyrrhine (e.g., Cebus) fetuses, gamma(1) at the ancestral distance from epsilon is down-regulated, whereas gamma(2) at increased distance is up-regulated. Catarrhine gamma(1) and gamma(2) acquired longer distances from epsilon (14 and 19 kb, respectively), and both are up-regulated throughout fetal life with gamma(1)'s expression predominating over gamma(2)'s. On enlarging the platyrrhine expression data, we find Aotus gamma is embryonic, Alouatta gamma is inactive at term, and in Callithrix, gamma(1) is down-regulated fetally, whereas gamma(2) is up-regulated. Of eight mammalian taxa now represented per taxon by embryonic, fetal, and postnatal beta-type globin gene expression data, four taxa are primates, and data for three of these primates are from this laboratory. Our results support a model in which a short distance (<10 kb) between epsilon and the adjacent gamma is a plesiomorphic character that allows the LCR to drive embryonic expression of both genes, whereas a longer distance (>10 kb) impedes embryonic activation of the downstream gene.
