Registered outcomes4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Motility index | 4 hours | Motility index (MI) is a calculated outcome, based on the formula: frequency/(10 x amplitude). Frequency and amplitude are secondary outcome measures as described below. The analysis is undertaken by attaching myometrial strips between an isometric force transducer and the base of an organ bath chamber. |
| Secondary | Amplitude of contraction | 4 hours | The maximum extent of uterine muscle and umbilical vessel contractions, measured in grams (g). The analysis is undertaken by attaching myometrial strips and umbilical vessel rings between an isometric force transducer and the base of an organ bath chamber. |
| Secondary | Frequency of contraction | 4 hours | The number of contractions in uterine muscle (myometrium) and umbilical vessel rings over 10 minutes, spontaneously and in response to an agonist. The analysis is undertaken by attaching myometrial strips and umbilical vessel rings between an isometric force transducer and the base of an organ bath chamber. |
| Secondary | Integrated area under response curve (AUC) | 4 hours |
