Understanding Suboptimal Insulin Use in Type 1 and Type 2 Diabetes: A Cross-Sectional Survey of People with Diabetes.
Article in Patient preference and adherence, 2025. 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
Purpose: This analysis aimed to document suboptimal insulin dosing (missed or skipped and mistimed basal and/or bolus) in people with diabetes (PwD), including type 1 diabetes (T1D) and type 2 diabetes (T2D). Additionally, barriers and solutions for optimal insulin dosing were explored. Patients and Methods: This multinational, cross-sectional, online survey was conducted in the United States, the United Kingdom, and Germany. Eligible PwD with T1D or T2D used an analog insulin pen. Data were analyzed using descriptive statistics. Results: A total of 1150 PwD (T1D: 300; T2D: 850) were included. Overall, a proportion of PwD reported missing 1 or more basal (48.2%) or bolus dose (59.6%) in the past 30 days. Among those who reported missing doses, the average number [standard deviation] was 3.6 [3.6] basal doses and 4.6 [7.4] bolus doses. PwD reported forgetting, being too busy/distracted, and finding it too complicated or burdensome as key reasons for missed doses. A proportion of PwD reported mistiming 1 or more basal (45.7%) dose or bolus (53.6%) dose in the past 30 days. Among those who reported mistiming doses, the average was 3.9 [4.0] basal and 5.1 [8.1] bolus doses. Key reasons reported for mistiming doses included being too busy or distracted, being out of routine, or having an unexpected or earlier/later-than-expected meal. Conclusion: Suboptimal insulin use is prevalent among PwD, with nearly half of participants reporting missed or mistimed doses in the past 30 days. Results indicate the need for support to help PwD self-manage the complexity of insulin treatment and to improve outcomes due to suboptimal insulin dosing. Such support might include devices that record measurements and dosing and provide feedback.
