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

aimsWe sought to compare the MiniMed™ 770G to the 780G insulin pump for glycemic control and quality of life in Japanese adults with T1D over a one-year period.

methodsThirty-six adults with T1D who switched from the MiniMed™ 770G to the 780G system were analyzed over 48 weeks using continuous glucose monitoring data, retrospectively. The percentages of time within the target glucose range (70-180 mg/dL), time above 180 mg/dL, and time below 70 mg/dL were compared before and after switching. Quality of life (QOL) scores were also evaluated in 39 patients using a validated questionnaire, prospectively.

resultsAfter switching to the MiniMed™ 780G, the time within the target glucose range significantly increased from 71.6 ± 12.4% to 76.1 ± 10.2% (P < 0.01), while the time above 180 mg/dL decreased from 25.2 ± 13.4% to 21.0 ± 11.0% (P < 0.01). The time below 70 mg/dL did not differ significantly overall, but nocturnal hypoglycemia decreased from 4.9% to 2.7% (P = 0.02). Glycated hemoglobin improved from 7.2 ± 0.8% to 7.0 ± 0.7% (P < 0.01). Although the total QOL score did not change significantly, the subscales reflecting anxiety and treatment satisfaction improved significantly.

conclusionsSwitching from the MiniMed™ 770G to the 780G system in Japanese adults with T1D improved both glycemic control and treatment-related QOL, supporting the clinical usefulness of the 780G in real-world clinical practice. This study provides the first one-year real-world evidence of MiniMed™ 780G use in Japan.
