Additional file 6. Statistical analysis for ARGs. The first column indicates the ARGs to be compared among samples, while the second column indicates the ARG class they belongs to. Next columns (until the column titled Kruskal p-value, not included) indicate average values for each sample group being compared. Kruskal p-value columns indicate the p-values for the comparison between sample groups, which are presented for each surface type and each processing room on the sheets surface_time and room_time respectively. The subsequent columns indicate p-values from the Wilcoxon pair-wise test for each pair of sample groups, which are also indicated on the column head. Statistical analyses performed by sampling time are presented on the time sheet, by sampling time for each surface type on the surface_time sheet, by surface type for each of the three time groups on the TX_surface sheets, by sampling time for each processing room on the room_time sheet, and by processing room for each of the three time groups on the TX_room sheets. NaN means not a number, and indicates those cases where statistical analyses could not be performed due to zero values on each sample to be compared.

附加文件6：抗生素抗性基因（Antibiotic Resistance Genes, ARGs）统计分析。第一列为需在各样本间进行比较的抗生素抗性基因，第二列为其所属的ARG类别。后续列（直至标为Kruskal检验p值的列之前，不含该列）为各待比较样本组的平均值。Kruskal检验p值列代表样本组间比较的p值，其中surface_time工作表与room_time工作表分别对应各表面类型与各处理室的比较结果。后续列则为各样本组两两比较的威尔科克森检验p值，列标题亦标注了对应的比较组信息。本次统计分析按多维度展开：按采样时间的分析结果见于time工作表；按各表面类型结合采样时间的分析结果见于surface_time工作表；按三种时间分组分别结合表面类型的分析结果见于TX_surface系列工作表；按各处理室结合采样时间的分析结果见于room_time工作表；按三种时间分组分别结合处理室的分析结果见于TX_room系列工作表。NaN代表非数值（not a number），用于标注因待比较的各组样本中存在零值而无法开展统计分析的情形。
