Table 3. Sensory Screening.

	Progesterone	Placebo
	n/N children (%)	n/N children (%)	Effect size (95% CI), p-value
Neonatal hearing screening *
Either ear fail	41/302 (14)	31/301 (10)	1.38 (0.81–2.35), 0.23
Preschool vision screening **
Either eye fail	70/250 (28)	71/263 (27)	1.04 (0.67–1.64), 0.85

*Screeners record the outcome of the first screen of each ear as pass, fail/refer, or not done/incomplete.

**Preschool vision screening includes an assessment of visual acuity and ocular movement. The outcome of screening for each eye is recorded as pass, refer or ongoing follow-up (both indicating failing screening), or recall (indicating screening could not be satisfactorily completed).
