First generation injection device was complex. There was no run-in period determined by researcher. Not a standardized method of care | Holman et al. (2017a) |
Harmony outcomes (9463) | Albiglutide (30 or 50 mg s/c weekly) | 0.78 (0.68–0.90) p < 0.0001 | 0.93 (0.73–1.19) p < 0.58 | 0.85 (0.70–1.04) p < 0.113 | Reduced the potential of CV complications. Improved cardiovascular outcomes for T2DM patients. | Short follow up. 25% of participants discontinued the study prior to completion. Microvascular complications were not noted. Urinary albumin excretion and lipids were no measured. | Hernandez et al. (2018) |
REWIND (9901) | Dulaglutide (1.5 mg per week s/c) | 0.88 (0.79–0.99) p < 0.026 | 0.91 (0.78–1.06) p < 0.21 | 0.93 (0.77–1.12) p < 0.46 | Lowers CV outcomes within 5 years. Lowers blood pressure. Increases weight loss. Lowers glucose levels while preventing risk of hypoglycemia | Over 25% of participants stopped using dulaglutide before study was completed. | Gerstein et al. (2019) |
EMPA-REG (7020) | Empagliflozin (10–25 mg once daily) | 0.86 (0.74–0.99) | 0.62 (0.49–0.77) p < 0.001 | 0.65 (0.5–0.85) p < 0.002 | Lowered the rate of primary composite CV outcome and death from any cause when studying the drug added to standard care | The discontinuation rate of both groups very similar | Zinman et al. (2015) |
DAPA-HF (4744) | Dapagliflozin (10 mg once daily) | 0.74 (0.65–0.85) p < 0.001 | 0.82 (0.69–0.98) | 0.70 (0.59–0.83) | Reduces the risk of worsening CV conditions compared to the placebo. The adverse event rate did not differ | Inclusion and exclusion criteria were very particular which could have decreased the generalizability of the study. The study also had limited diversity, also lowering generalizability | McMurray et al. (2019) |
CANVAS PROGRAM (10142) | Canagliflozin (100 mg and 300 mg orally daily) | 0.86 (0.75–0.97) p < 0.60 | 0.9 (0.7–1.15) | 0.67 (0.52–0.87) | Decreases risk of mortality from CV complication, non-fatal MI and non-fatal stroke. Increased risk of amputation | Low levels of end-stage renal disease. Increase use of glucose-lowering solutions in the placebo group may have resulted in risks or benefits of Canagliflozin | Neal et al. (2017) |
EMPEROR-reduced (3730) | Empagliflozin (10 mg daily) | 0.75 (0.65–0.86) p < 0.001 | 0.92 (0.75–1.12) | 0.69 (0.59–0.81) | Reduction in the risk of CV death or hospitalization for HF compared to the placebo.

(2019) |
