Four sarcomeric myosin heavy chain genes are expressed by human fetal skeletal muscle cells differentiating in culture.

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
Expression of four sarcomeric myosin heavy chain (MHC) genes was examined in continuously passaged human fetal (18-22 week) skeletal myoblasts and in myoblasts induced to differentiate by low mitogen medium. Although embryonic MHC mRNA predominated at all time points following induction, three additional MHC genes were expressed at lower levels. These consisted of perinatal, slow, and fast skeletal MHC genes. Temporal regulation of MHC gene expression was observed. In myoblasts and early induced cultures, embryonic and fast transcripts were detected, accompanied in later induced cultures by the accumulation of perinatal and slow MHC transcripts. In situ hybridization analysis of uninduced cells revealed that sarcomeric MHC transcripts originated from a small population of spontaneously fused multinucleated cells. Taken together, these observations demonstrate that human fetal myoblasts induced to differentiate in culture execute a developmental program that includes temporally regulated expression of four distinct sarcomeric MHC genes.
