Contributions of authors

Hugo Farne assessed the updated database search for studies for inclusion, extracted data (duplicated by Chris Cates), conducted the analysis and wrote the updated review with input from Chris Cates. Chris Cates performed the updated search of ClinicalTrials.gov, which both authors reviewed separately for studies for inclusion.

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.

On tiotropium/olodaterol combination, at six months there were 55 SGRQ (St George's Respiratory Questionnaire) responders out of 100 (95% confidence interval 52 to 57) compared to 48 out of 100 on tiotropium alone.

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
