Cancer risks among studies of medical diagnostic radiation exposure in early life without quantitative estimates of dose

Fig. 1. Meta-regression for studies of in utero and postnatal exposure. Restricted maximum likelihood (REML) fits to odds ratio or relative risk by calendar year midpoint of study data ascertainment range (for <1950, 1950-1959, 1960-1969, 1970-1979, 1980-1989, 1990+). For each panel plots are shown for (a) the four cancer endpoints analysis (leukaemia, lymphoma, brain/CNS cancer, other cancer) and (b) the any cancer endpoint analysis, for each in utero exposure study. Dashed red line is odds ratio/relative risk = 1.Unlabelled Image
