Excess relative risk (ERR) estimates from the A-bomb survivors and from selected studies of persons exposed to protracted low-LET external ionizing radiation.

* Doses are external colon dose in mGy for Mayak workers, weighted colon dose in mGy for the atomic bomb survivors, Hp(10) in mSv for the 15-country and NRRW studies.(Hp(10) is the equivalent dose at a tissue depth of 10 mm beneath a dosimeter); stomach dose in mGy for the Techa river cohort† 90% confidence intervals used for comparison with published results in the 15-country and NRRW studies†† weighted average with weights of 0.75 for men and 0.25 for women to reflect the sex ratio in the Mayak worker cohort‡ These populations are predominantly male§ The estimate presented here is based on the 15-country study results withwith the Canadian data excluded ([29], page 405).). This estimate was used because of concerns about the Canadian data usedused in that study. This concerns have beenbeen supported by the recently published re-analysis of the Canadian workerworker data given in [34]. The ERR/SvSv estimate for using all of the 15-country data is 0.59 (95% CI 29], page 403).** There was no evidence that risk differed by sex in this cohort.Excess relative risk (ERR) estimates from the A-bomb survivors and from selected studies of persons exposed to protracted low-LET external ionizing radiation.

本数据集的剂量信息如下：马亚克工人的剂量为外照射结肠剂量（单位：毫戈瑞，mGy）；原子弹幸存者的剂量为加权结肠剂量（单位：毫戈瑞，mGy）；15国研究与NRRW研究的剂量为Hp(10)（Hp(10)指剂量计下方10mm组织深度处的当量剂量，单位：毫西弗，mSv）；捷恰河队列的剂量为胃剂量（单位：毫戈瑞，mGy）。
†：90%置信区间用于与15国研究及NRRW研究††中已发表的结果进行对比；
††：采用男性权重0.75、女性权重0.25的加权平均值，以反映马亚克工人队列‡的性别比；
‡：该类人群以男性为主§；
§：本文呈现的估算值基于排除加拿大数据后的15国研究结果（[29]，第405页）。
之所以采用该估算值，是因为对该研究中使用的加拿大数据存在疑虑。该疑虑已得到[34]中最新发表的加拿大工人数据重新分析结果的支持。纳入全部15国研究数据的ERR/Sv估算值为0.59（95%置信区间，[29]，第403页）**。该队列未发现风险存在性别差异的证据。本数据集包含原子弹幸存者以及经筛选的持续性低LET外照射电离辐射暴露人群的超额相对风险（ERR, Excess relative risk）估算值。
