From: Reproducibility of clinical research in critical care: a scoping review
Reproducibility component | Definition |
---|---|
Unique clinical practice | A specific intervention applied to patients with a specific target condition (e.g., therapeutic hypothermia for patients with traumatic brain injury) |
Reported effect of clinical practice | |
 Efficacy | For the primary outcome, statistically significant increased risk of a positive outcome, or decreased risk of a negative outcome |
 Harm | For the primary outcome or any pre-specified secondary or safety outcome, statistically significant increased risk of a negative outcome, or decreased risk of a positive outcomea |
 Lack of efficacy | For the primary outcome, a non-statistically significant change |
Type of results reproducibility [12] | |
 Re-test reproduction attempt | For a given clinical practice, a study that re-examined the results of an original study in another group of participants using methodology identical to that of the original studyb |
 Approximate reproduction attempt | For a given clinical practice, a study that re-examined the results of an original study in another group of participants using methodology with minor changes to the population, setting, treatment, outcomes, and/or analyses relative to the original studyb |
Reproducibility classification | |
 Original study | First randomized controlled trial to examine the effects of a clinical practicec |
 Reproduction attempt | Re-test or approximate reproduction attempt for an original study |
 Consistent effect estimate between original study and reproduction attempt | Clinical practice effect reported in the reproduction attempt was congruent with that in the original study: - Efficacy/efficacy - Lack of efficacy/lack of efficacy - Harm/harm |
 Inconsistent effect estimate between original study and reproduction attempt | Clinical practice effect reported in the reproduction attempt was different from that in the original study: - Efficacy/harm - Efficacy/lack of efficacy - Harm/lack of efficacy - Harm/efficacy - Lack of efficacy/harm - Lack of efficacy/efficacy |
