Figure 2:

Comparison of dietary calcium intake in participants with type 1 diabetes (T1D) versus healthy controls assessed by food questionnaire (n=8) and dietary recall (n=2). Error bars represent standard deviation and were taken directly from manuscripts. None of the studies reported a significant difference in calcium intake in T1D vs control participants. Studies by Simmons et al., Janner et al., and Weber et al. did not have a control group. Data for Valerio, Moyer-Mileur, and Janner studies represent average of reported sex-specific values, in all cases there was no difference by sex. Values below the X-axis represent mean calcium intake for T1D and control participants. Age of study participants is reported as range, if available, otherwise as mean ± standard deviation
