Differences between protocol and review

We have updated the text of this review to reflect new methods of reporting for Cochrane reviews and have included the GRADE assessment and summary of findings Table for the main comparison. We have expanded methodological aspects of the review as per standard Cochrane Neonatal Review Group procedure.

Outcome

El uso y la enseñanza del modelo PICO están muy extendidos en el ámbito de la atención sanitaria basada en la evidencia para formular preguntas y estrategias de búsqueda y para caracterizar estudios o metanálisis clínicos. PICO son las siglas en inglés de cuatro posibles componentes de una pregunta de investigación: paciente, población o problema; intervención; comparación; desenlace (outcome).

Para saber más sobre el uso del modelo PICO, puede consultar el Manual Cochrane.

Bone fracture (neonatal) ‐ not measured

This was not a prespecified outcome; included study did not report this outcome

Growth (childhood/adulthood) ‐ not measured

Included study provided no follow‐up into childhood

Bone mineral density (infant/childhood/adulthood) ‐ not measured

Included study provided no follow‐up into childhood

Fracture (childhood/adulthood) ‐ not measured

Included study provided no follow‐up into childhood

*Risk in the intervention group (and its 95% confidence interval) is based on assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI)

CI: confidence interval; OR: odds ratio; RR: risk ratio

GRADE Working Group grades of evidence
High quality: We are very confident that the true effect lies close to the estimate of effect
Moderate quality: We are moderately confident in the effect estimate: The true effect is likely to be close to the estimate of effect but may be substantially different
Low quality: Our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of effect
Very low quality: We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect

aRisk of bias: insufficient evidence to judge methods of randomisation, allocation concealment or blinding of personnel ‐ downgraded one level

bImprecision: wide confidence intervals and data from a single small study ‐ downgraded one level

cImprecision: evidence from a single small study ‐ downgraded one level
