Advances in insulin pump systems lead to stepwise improvements in treatment satisfaction in people with type 1 diabetes: A single-center retrospective study.
Article in Journal of diabetes investigation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionTransition from the MiniMed™ 770G hybrid closed loop (HCL) to the MiniMed™ 780G advanced hybrid closed loop (AHCL) insulin pump system has been demonstrated to improve glycemic control in people with type 1 diabetes (T1D). However, evidence regarding changes in treatment satisfaction following insulin pump upgrades remains limited to date.
methodsPeople with T1D who underwent sequential insulin pump transitions from the MiniMed™ 640G with predictive low glucose management (PLGM) to the 770G HCL and subsequently from the 770G HCL to the 780G AHCL were retrospectively analyzed. Changes in treatment satisfaction were assessed using the Diabetes Treatment Satisfaction Questionnaire status (DTSQs) and change (DTSQc), together with clinical and continuous glucose monitoring metrics.
resultsDTSQs scores remained unchanged after transition from the 640G PLGM to the 770G HCL and from the 770G HCL to the 780G AHCL. In contrast, DTSQc scores significantly increased after transition from the 770G HCL to the 780G AHCL (13; range: 12-16; P < 0.0001) and were significantly higher than those observed after transition from the 640G PLGM to the 770G HCL. Following the transition to the 780G AHCL, HbA1c significantly decreased and TIR
conclusionsIn people with T1D, transition from the 770G HCL to the 780G AHCL significantly improved treatment satisfaction, with greater benefits than those observed during the transition from the 640G PLGM to the 770G HCL.
