Myometrial tissue gene expression studies analyzed in this work.

Study	Platform	Sample groups	Group size	Clinical definition of labor
Warwick	RNA-seq	Non-labor (W-IL) In-labor (W-IL)	N = 5 N = 5	Regular contractions (<3 min apart), membrane rupture, and cervical dilation (>2 cm)
London	RNA-seq	Non-labor (L-NL) Early-labor (L-ILEa) Established-labor (L-ILEs)	N = 8 N = 8 N = 6	Cervical dilation < 3cm (L-ILEa) Cervical dilation > 3cm (L-ILEs)
Detroit	Microarray	Non-labor (W-NL) In-labor (W-IL)	N = 20 N = 19	Contractions (<10 min apart) and cervical dilation requiring hospitalization

Three gene expression datasets collected from publicly available sources or collaborators are shown. Sample groups and names are consistent with the acronyms listed in column three throughout the paper. Clinical definitions of labor represent how each sample was called phenotypically, based on the patient’s clinical presentation at the time of cesarean section, as chosen by the researchers collecting the samples.
