| Abstract |
Adherence and persistence to antidiabetes medications are important to control blood glucose levels among individuals with type 2 diabetes mellitus (T2D). The objective of this study was to compare adherence and persistence over a 12-month period between patients initiating saxagliptin and patients initiating linagliptin, two dipeptidyl peptidase-4 inhibitors. This retrospective cohort study was conducted in MarketScan(®) Commercial and Medicare Supplemental claims databases. Patients with T2D initiating saxagliptin or linagliptin between January 1, 2009, and June 30, 2013, were selected. Patients were required to be at least 18 years old and have 12 months of continuous enrollment prior to and following initiation. Adherence and persistence to initiated medication were measured over the 12 months after initiation using outpatient pharmacy claims. Patients were considered adherent if the proportion of days covered was ≥0.80. Patients were considered nonpersistent (or to have discontinued) if there was a gap of >60 days without initiated medication on hand. Multivariable logistic regression and multivariable Cox proportional hazard models were fit to compare adherence and persistence, respectively, between the two cohorts. There were 21,599 saxagliptin initiators (mean age 55 years; 53% male) and 5,786 linagliptin initiators (mean age 57 years; 54% male) included in the study sample. Over the 12-month follow-up, 46% of saxagliptin initiators and 42% of linagliptin initiators were considered adherent and 47% of saxagliptin initiators and 51% of linagliptin initiators discontinued their initiated medication. After controlling for patient characteristics, saxagliptin initiation was associated with significantly greater odds of being adherent (adjusted odds ratio =1.212, 95% CI 1.140-1.289) and significantly lower hazards of discontinuation (adjusted hazard ratio =0.887, 95% CI 0.850-0.926) compared with linagliptin initiation. Compared with patients with T2D who initiated linagliptin, patients with T2D who initiated saxagliptin had significantly better adherence and persistence. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 05 August 2016.
All research outputs
#16,735,892
of 25,394,764 outputs
Outputs from Patient preference and adherence
#1,001
of 1,759 outputs
Outputs of similar age
#242,269
of 381,115 outputs
Outputs of similar age from Patient preference and adherence
#53
of 78 outputs
Altmetric has tracked 25,394,764 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,759 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.5. This one is in the 39th percentile – i.e., 39% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 381,115 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 33rd percentile – i.e., 33% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 78 others from the same source and published within six weeks on either side of this one. This one is in the 30th percentile – i.e., 30% of its contemporaries scored the same or lower than it.
