1 · What the graph read from it

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.

2 · The registry

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

aimTo evaluate the persistence with oral antidiabetic drug (OAD) treatment characterized by drug class, patient characteristics and severity of renal impairment (RI) in patients with type 2 diabetes (T2DM) in Japan. MATERIALS AND

methodsThis retrospective, observational study extracted data from a large-scale hospital database (April 2008 to September 2016). Patients with T2DM aged ≥40 years on the day of their first prescription (index date) of any OAD (biguanides [BGs], thiazolidinediones [TZDs], sulphonylureas [SUs], glinides, dipeptidyl peptidase-4 [DPP-4] inhibitors, or α-glucosidase inhibitors [α-GIs]) available between January 1, 2014 and September 30, 2016 were identified. Sodium-glucose co-transporter-2 inhibitors were not available at study initiation. Treatment persistence was assessed by Kaplan-Meier survival curves. Patients were also categorized by RI status using estimated glomerular filtration rate: ≥90 mL/min/1.73 m

resultsWe identified 206 406 index dates from 162 116 eligible patients. The largest number of index dates (91634) was observed for DPP-4 inhibitors, followed by BGs, SUs, α-GIs, glinides and TZDs. Treatment persistence was longest for DPP-4 inhibitors (median 17.0 months, 95% confidence interval [CI] 16.4-17.5) and BGs (median 17.3 months, 95% CI 16.6-18.2), and shortest for α-GIs (median 5.6 months, 95% CI 5.4-5.9) and SUs (median 4.3 months, 95% CI 4.2-4.6). Persistence was longest with DPP-4 inhibitors at all RI stages (G1-G4+), followed by BGs at stages G1/G2.

conclusionsThe longest OAD persistence was observed for BGs and DPP-4 inhibitors at RI stages G1/G2, and for DPP-4 inhibitors at RI stages G3/G4+.
