Infant sleep education,
does it really help with Reduced objective night waking measured by actigraphy?
research showsThe grade is D. The registered primary outcome was one composite met when a parent reported a severe sleep problem or the five-day mean actigraphic waking count was at least twice nightly. The actigraphic criterion applied to 93/96 (96.9%) versus 94/96 (97.9%), nearly every infant. Parent-rated severe problems fell from 15/107 (14%) to 4/108 (4%), but an infant actually waking less and a parent feeling less burdened are different claims, giving D with 32 points.
ads claimMarketing must not convert parents feeling less burdened into infants objectively waking less. Both can matter, but they are not interchangeable outcomes.
Useful facts when choosing a product
- ISRCTN42169337 was registered on 2009-07-14 before recruitment began in September 2009.
- The actigraphic criterion was 93/96 (96.9%) versus 94/96 (97.9%), a simple difference of -1.0 percentage point without a valid reported confidence interval.
- Adjusted mean nightly wakes differed by -0.2 wakes (95% CI -1.32 to 0.91, P=.72), while the parent-rating risk difference was -10 percentage points (-16.8 to -2.2).
What the research actually shows
Hall and colleagues randomized 235 families to sleep education, 117, or infant-safety education, 118. ISRCTN42169337 was registered on 2009-07-14, before recruitment began in September 2009. The primary outcome was a single composite met by either parent-rated severe sleep difficulty or at least two mean nightly actigraphic wakes over five days; the individual measures were also listed as major secondary outcomes. Parent ratings were 4/108 versus 15/107, unadjusted RR 0.26 (95% CI 0.09 to 0.77), baseline-adjusted RR 0.30 (0.11 to 0.84), and risk difference -10 percentage points (-16.8 to -2.2). The actigraphic criterion occurred in 93/96 versus 94/96, a simple difference of -1.0 percentage point for which the paper gives no valid confidence interval. Adjusted mean nightly wakes differed by -0.2 wakes (95% CI -1.32 to 0.91, P=.72). The abstract and body internally mislabel this mean difference as a risk difference of -0.2%.
Why this is classified as D (32)
The actigraphic component of the composite primary outcome applied to nearly every infant and objective waking was null. The positive finding was an unblinded parent rating, with attrition from actigraphy analysis, giving D with 32 points.
Counterpoint. This verdict does not deny improvements in parental coping, fatigue, or mood. It addresses only the narrow claim of reduced objective infant night waking.

| Endpoint | P | Patient-reported treatment goal - the symptom is the goal |

The scoring table and the verdict agree (D).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Reduced actigraphic night waking | D | There was no between-group reduction, 96.9% versus 97.9%. |
| Reduced parent-rated severe sleep problems | C | Rates were 4% versus 14%, but parents knew allocation. |
