Relevance
1.Is the objective of the article comparing
therapeutic interventions similar to your
clinical dilemma?
• Yes, the aim of the study was to find out if
radiofrequency thermal ablation can prevent
recurrences in HCC
Validity Guides for treatment:
1. Was the assignment of patients to
treatment randomized? Was randomization
concealed?
• No, there was no randomization of patients to
control and treatment group. The comparison
was made between the T-cell response of the
patient before and after radiofrequency
ablation.
Validity Guides for treatment:
• 2.Was the follow-up sufficiently long and
complete?
• Follow up was done 6 months after therapy
which may not be enough.
Validity Guides for treatment:
3.Was the data analyzed on an intention-totreat basis?
• Yes
4. Was there adequate blinding of subjects and
researchers?
• No
Validity Guides for treatment:
5.Were there similar baseline characteristics in
each group?
• All patients were treated for HCC in cirrhosis
• Other baseline characteristics were not
uniform in all patients
Validity Guides for treatment:
6. What is the magnitude of treatment effect?
• 1 months after radioablation, T-cell response
was measured
• Final outcome measured was recurrence of
the tumor
Over all is the study valid?
• No
External validity
1.Are the results of the study applicable to my
patient?
• Yes
2.Were all clinically important outcomes
considered?
• Yes
3.Is treatment feasible?
• Yes
