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.

*The risk with placebo was the average risk in the placebo group (i.e. the number of participants with events divided by total number of participants of the placebo group included in the meta‐analysis). The risk in the metoprolol group (and its 95% CI) is based on the assumed risk in the placebo group and the relative effect of the intervention (and its 95% CI).

Abbreviations: AAA: abdominal aortic aneurysm; CI: confidence interval; MI: myocardial infarction; OR: odds ratio; RCT: randomised controlled trial

GRADE Working Group grades of evidence
High quality: we are very confident that the true effect lies close to that of the estimate of the effect
Moderate quality: we are moderately confident in the effect estimate: The true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different
Low quality: our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the 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

1Death from all causes.
2Quality of evidence downgraded to low for imprecision due to low number of events, small sample size and wide CIs.
3Fatal MI, fatal stroke and other vascular deaths.
4Death due to abdominal aortic aneurysm.
5Nonfatal MI, nonfatal stroke, or transient ischaemic attack.
