Dental Pain |
---|
Jena et al., 20136 |
---|
Appropriate and clearly focused research question Initial pain was similar between groups at baseline Inclusion criteria, study interventions, outcome measures clearly described
|
Randomization and concealment methods were not adequately described Blinding procedures were not adequately described Baseline patient characteristics were not well reported Unclear whether all patients completed the study and if the analysis was based on intention to treat. None of the results demonstrated statistical significance
|
Aggarwal, 20107 |
---|
Appropriate and clearly focused research question Only difference between groups is treatment under investigation Randomization and concealment methods were well described Blinding procedures were well described Baseline patient characteristics were reported Power and sample size calculation provided Inclusion criteria, study interventions, outcome measures clearly described Low discontinuation rate

Non-Dental/Non-Cancer |

Ortiz, 20108 |
---|
|
Randomization and concealment methods were not adequately described Blinding procedures were not adequately described Baseline patient characteristics were not well reported Unclear how many patients were originally randomized in the study Statistical analyses methods not provided Exclusion criteria not provided

Kaeding et al., 20049 |
---|
Appropriate and clearly focused research question Randomization methods were well described Baseline patient characteristics were reported
|
Patients were not blinded, only nurse assessor was blinded Statistical measures of dispersion and confidence intervals were not provided None of the results demonstrated statistical significance Only exclusion criteria was specified
