Reliability or difference between “inter-subject” (n = 7) and “pool” studies at each site (marshland, marina, fishing harbour and seaport-Maritime) at D21 for the 4 biomarkers of exposure (GST, SOD, MDA and Laccase).

Green shading represents 0–20% difference, red shading represents 20–30% difference and yellow shading represents more 30% difference. Negative percentages are lower rates in the “inter-subject” study compared to the “pool” analysis.

绿色着色区域对应百分比差异处于0%至20%的区间，红色着色区域对应百分比差异处于20%至30%的区间，黄色着色区域对应百分比差异超过30%的情况。负值表示在「受试者间（inter-subject）」研究中，所得比率低于「合并（pool）」分析的结果。
