Management of Spontaneous Labor in Primigravidae: Labor Scale versus WHO Partograph (SLiP Trial) Randomized Controlled Trial.

Objective: We aimed to compare maternal and neonatal outcomes of spontaneous term labor among primigravidae who were monitored by the novel labor scale versus the World Health Organization (WHO) partograph.

Study Design: A single center, double-blinded randomized trial had been conducted between July 2015 and June 2016. Nulliparous women in spontaneous labor with singleton term pregnancies were randomized to either labor scale or the WHO partograph for management of labor.
