Summary of Study Characteristics Evaluated in the Effectiveness Review: PICOTS

Development of clinical studies of effectiveness of medical interventions is guided by the PICOTS (population, interventions, comparators, outcomes, timing, and setting) framework. These items are critical elements that will help to answer important clinical questions.

In the comparative effectiveness review, the clinical study literature was reviewed and summarized by using the PICOTS framework. The evidence concerning the outcomes identified here was examined in detail, and strength-of-evidence determinations were made only for these key outcomes.

  • All risk factors

Interventions: Progestogens

  • All formulations, routes, and doses

Comparators: Placebo or no active intervention

  • Preterm birth incidence
  • Maternal, fetal, and neonatal health outcomes
