Please be advised that due to the high volume of submissions, the ANZCTR is currently experiencing delays in processing submissions from those outside of Australia and New Zealand. As the ANZCTR is funded by Australia and New Zealand, we must prioritise submissions from these countries first. International submissions should allow additional time for registration. Apologies for any inconvenience caused.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
To use continuous glucose monitoring (CGM) to profile the glycemic impact of commonly prescribed Glucocorticoid (GC) regimens. CGM will be applied for 3 days prior to the first dose of GC and continued for 3 days following GC administration at per the prescribed dose frequency (total duration 6 days)

Not applicable
Comparator / control treatment
Internal control; continuous glucose monitoring before and after administration of glucocorticoid

Statistical methods / analysis
Descriptive statistics will be percentages for categorical data, mean +/- SD for normally distributed continuous data and median (interquartile range (IQR)) for non-normally distributed continuous or ordinal data. Paired and unpaired t-tests will be used to detect the differences in glycaemia and glycaemic variability between GC therapy and no GC therapy. The Wilcoxon rank test will be used to detect differences in ordinal data. Area under the glucose concentration-time curve will be measured using the trapezoidal rule. Results will be calculated using GraphPad Prism version 6.0a for Mac OS X, GraphPad Software (La Jolla California, USA). P values <0.05 will be considered statistically significant.
