We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

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
All elective patients (non-diabetic/diabetic) will be invited on the day of their routine visit to participate in the present study.
If the patient agrees to participate, a single 10ml blood sample will be collected for subsequent analysis.
Blood collection will require no more than 10 minutes of the participant's time.

Statistical methods / analysis
Sample size rationale:
Previous studies using the same technique (Springhorn C et al 2012 and Prashilla S 2016), have reported appropriate samples sizes of approximately 30 per group. Although Menart-Houtermans and collegues (2014) have used sample sizes ranging from 60-132 patients to count white blood cells (WBC), the technique employed automated cell counting, which is less reproducible and precise (Tuchin V et al 2011). Based on an expected increase in relevant WBC levels of approximately 20% (power 80%, P = 0.05), 30 T1D 30 T2D patients attending the Diabetes Clinics at the Baker Heart and Diabetes Institute, and 30 non-diabetic individuals from October 2018 will be invited to participate in the study.

Statistical analysis:
For all analyses, a one-way ANOVA will be employed with either a Tukey's or Dunnett's post-hoc test to compare the mean of all experimental groups to one another. Data will be displayed as mean (+/- SD).
Due to the exploratory nature of this study, distribution analyses will be conducted on all data to ensure the correct statistical test is conducted.

Brief summary
We are aiming to assess the potential differences in immune cell proportions between healthy and diabetic individuals. We hope to identify these differences in order to decipher the gap in knowledge regarding the immune system, diabetes and heart failure.
