Table 1.

Reported data in chronological order of publication of the surveyed studies that carried out exercise trials. GS stands for Gold Standard glucose reference. $\Delta$MARD $=MAR{D}_e-MAR{D}_r$ where $MAR{D}_e$ is the MARD of the samples within exercise periods and $MAR{D}_r$ is the counterpart for the samples during rest periods. Asterisks (*) indicate that $MAR{D}_r$ was extracted from the articles mentioned in Table 2. The shaded rows correspond to those papers that reported necessary data to assess sensor accuracy during exercise, 17 in total. The labels that will later be used in the graphics to uniquely identify a study and branch have also been added to the MARD exercise column.
