Relative differences between PFAA concentrations in 88 paired blood samples that were immediately processed or transported with a processing delay, stratified by the season of sampling.

PFAA: Perfluoroalkyl acidIQR: interquartile range95% confidence interval (95% CI).See Table 1 for specific PFAA abbreviations. Medians are not log-transformed.Median1 refers to immediately processed samples. Median2 corresponds to samples that were delayed and transported and processing. 36 samples were sampled in the winter, and 52 in the summer.Relative differences between PFAA concentrations in 88 paired blood samples that were immediately processed or transported with a processing delay, stratified by the season of sampling.

PFAA：全氟烷基酸（Perfluoroalkyl acid）；IQR：四分位距（interquartile range）；95%置信区间（95% CI）。具体PFAA缩写详见表1。中位数未进行对数转换。中位数1指代即刻处理的样本；中位数2对应延迟运输后再进行处理的样本。冬季采集样本36份，夏季采集52份。本数据集展示了按采样季节分层的88份配对血样中，即刻处理或延迟运输处理的全氟烷基酸浓度相对差异。
