Correlations observed between the RRD and the IL-6, IL-8, MCP-1, MIP-1β, and IP-10 with the duration of RRD. R1 with a solid regression line means Pearson's correlation coefficient when data of MH are not included, while R2 with a broken regression line is that when the data of MH are included as a duration of the 0 week. While only R1 of MIP-1β exhibited a significant correlation to IL-8, statistical significance was observed for all of R2s.
