Pyo, Kim, and Cho: Response to Comment on “Prognostic Role of Claudin-1 Immunohistochemistry in Malignant Solid Tumors: A Meta-Analysis”
This study aimed to elucidate the prognostic roles of claudin-1 immunohistochemistry in various malignant tumors through a meta-analysis. Data from all included studies were extracted by two independent authors (J.S.P. and N.Y.K.). Any disagreements for extracting data were resolved by consensus. In the present study, to review more articles, we used the narrow exclusion criteria. Therefore, discordance for the literature collection did not occur. We assessed the risk of bias for all included studies according to the Newcastle-Ottawa Scale. The detailed information was shown in Table 1. All data for survivals were a 5-year survival rate. If the extractable data only included the survival curve, survival rates at 5-year were obtained from the survival curve.
