Study characteristics | |||
Patient Sampling | The study was aimed to investigate the role of AFP for HCC in patients with advanced liver cirrhosis waiting for liver transplantation. During 10 years, 2074 adult liver‐surgery recipients were identified. They were divided into two groups as HCC and non‐HCC. Age range not reported. Males 71%. |
||
Patient characteristics and setting | |||
Index tests | AFP: ROC curve analysis showed that AUC of AFP was 0,693 having a cut‐off at 6,8 ng/mL with sensitivity of 64.5% and specificity of 64.5%. | ||
Target condition and reference standard(s) | HCC: all patients underwent orthotopic liver transplantation (OLT). | ||
Flow and timing | No information on interval between index test and reference standard | ||
Comparative | |||
Notes | No information on conflicts of interest | ||

Item | Authors' judgement | Risk of bias | Applicability concerns |
DOMAIN 1: Patient Selection | |||
Was a consecutive or random sample of patients enrolled? | No | ||
Was a case‐control design avoided? | Yes | ||
Did the study avoid inappropriate exclusions? | Unclear | ||
Could the selection of patients have introduced bias? | High risk | ||
Are there concerns that the included patients and setting do not match the review question? | High | ||
DOMAIN 2: Index Test (AFP) | |||
Were the index test results interpreted without knowledge of the results of the reference standard? | Yes | ||
If a threshold was used, was it pre‐specified? | No | ||
Could the conduct or interpretation of the index test have introduced bias? | High risk | ||
Are there concerns that the index test, its conduct, or interpretation differ from the review question? | Low concern | ||
DOMAIN 2: Index Test (US+AFP) | |||
DOMAIN 2: Index Test (US) | |||
DOMAIN 3: Reference Standard | |||
Is the reference standards likely to correctly classify the target condition? | Yes | ||
Were the reference standard results interpreted without knowledge of the results of the index tests? | Unclear | ||
Could the reference standard, its conduct, or its interpretation have introduced bias? | Unclear risk | ||
Are there concerns that the target condition as defined by the reference standard does not match the question? | High | ||
DOMAIN 4: Flow and Timing | |||
Was there an appropriate interval between index test and reference standard? | Unclear | ||
Did all patients receive the same reference standard? | Yes | ||
Were all patients included in the analysis? | Yes | ||
Could the patient flow have introduced bias? | Unclear risk |
