  2. 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

  3. 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.

  4. 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.

  5. Validity Guides for treatment: 3.Was the data analyzed on an intention-to- treat basis? • Yes 4. Was there adequate blinding of subjects and researchers? • No

  6. 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

  7. 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

  8. 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
