Signaling question | Comments | Response |
Was selection of exposed and non‐exposed cohorts drawn from the same population? | The exposed and unexposed cohorts were drawn from the same site and were all consecutive patients; however, the 50 unexposed participants all received treatment directly before the 50 exposed participants | PY |
Can we be confident in the assessment of exposure? | Cohorts were drawn from directly before and after the implementation of a new intervention protocol at the study site | DY |
Can we be confident that the outcome of interest was not present at the start of the study? | The outcomes of interest are all postoperative measures | DY |
Did the study match exposed and unexposed for all variables that are associated with the outcome of interest or did the statistical analysis adjust for these prognostic variables? | Yes, all variables associated with the outcome of interest were analyzed, and no statistically significant differences were found | DY |
Can we be confident in the presence or absence of prognostic factors? | There were no statistically significant differences found in clinical/baseline outcome measures prior to intervention | DY |
Can we be confident in the assessment of the outcome? | Yes, all measures used had been previously established as effective | DY |
Was the follow-up of cohorts adequate? | Data was collected through the participants 3-month (12 weeks) follow-up clinic visits; the intervention was completed during the perioperative period | PY |
Were co-interventions similar between groups? | It is clearly stated that all other anesthetic/analgesic interventions aside from the experimental intervention (percutaneous freezing of sensory nerves – cryoneurolysis) were identical between groups | DY |
*Possible Responses: Definitely Yes (DY), Probably Yes (PY), Definitely No (DN).
