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

backgroundSodium-glucose co-transporter 2 inhibitors (SGLT2i) has shown evidence of cardiovascular benefit in patients with type 2 diabetes mellitus (T2DM). Currently metformin is the guideline-recommended first-line treatment. We aimed to investigate the benefit of SGLT2i vs metformin as first-line therapy.

methodsElectronic medical records from Chang Gung Research Database during 2016-2019 were retrieved for patients with T2DM. Patients aged < 20, not receiving anti-diabetic medication, first-line treatment neither metformin nor SGLT2i were excluded. Primary outcomes were heart failure hospitalization, acute coronary syndrome, ischemic stroke, and all-cause mortality. Patients were followed up for events or December 31, 2019, whichever comes first.

resultsAfter exclusion criteria, a total of 41,020 patients with T2DM were eligible for analysis. There were 1100 patients with SGLT2i as first-line and 39,920 patients with metformin as first-line treatment. IPTW was used for propensity score matching. During one year follow-up, the hazard ratio (HR) of patients on SGLT2i as first-line treatment to patients on metformin as first-line treatment were HR 0.47 (95% CI 0.41-0.54, p < 0.0001) in heart failure hospitalization, HR 0.50 (95% CI 0.41-0.61, p < 0.0001) in acute coronary syndrome, HR 1.21 (95% CI 1.10-1.32, p < 0.0001) in ischemic stroke, and HR 0.49 (95% CI 0.44-0.55, p < 0.0001) in all-cause mortality.

conclusionsIn patients with T2DM, SGLT2i as first-line treatment may be associated with decreased events of heart failure hospitalization, acute coronary syndrome, and all-cause mortality, compared with metformin as first-line treatment. However, there may be an increased events of ischemic stroke using SGLT2i compared to metformin.
