Replacement Effects and Budget Impacts of Insurance Coverage for Sodium-Glucose Co-Transporter-2 Inhibitors on Oral Antidiabetic Drug Utilization.
Article in Clinical drug investigation, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
objectivesA new oral antidiabetic drug class, sodium-glucose co-transporter-2 inhibitors (SGLT-2 inhibitors), has been covered by national health insurance in Taiwan since May 2016. This study estimated the impacts of insurance coverage for SGLT-2 inhibitors on the replacement effects of antidiabetic drug use and the overall budget for antidiabetic drugs in Taiwan.
methodsAntidiabetic drugs were divided into nine categories based on the American Diabetes Association guidelines. We retrieved claims data from 2015 to 2017 for all patients diagnosed with diabetes mellitus from the National Health Insurance Research Database. An interrupted time series design and segmented regression were used to estimate the budget impact of insurance coverage for SGLT-2 inhibitors. Three scenarios were designed for the prescribing pattern for SGLT-2 inhibitors: (1) monotherapy, (2) metformin-based (m-based) drug prescriptions, and (3) metformin and sulfonylurea-based (m-s-based) drug prescriptions.
resultsFrom May 2016 to April 2017, the prescription rate for m-based SGLT-2 inhibitors increased from 0.43 to 3.50%, and the expenditure rate increased from 0.82 to 6.58%. We found that the prescription rates of m-based and m-s-based dipeptidyl peptidase-4 inhibitors (DPP-4 inhibitors) decreased by 6.23 and 11.51% following the initiation of insurance coverage for SGLT-2 inhibitors, respectively. Furthermore, there was a 5.95% increase in the overall budget impact of antidiabetic drugs 1 year following the initiation of insurance coverage for SGLT-2 inhibitors.
conclusionsBoth the prescription rates and expenditure rates for SGLT-2 inhibitors have increased since they have been covered by national health insurance in Taiwan, which significantly reduced usage of DPP-4 inhibitors but caused the positive growth of overall antidiabetic drug expenditures.
