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
introductionEffective insulin therapy relies on proper injection technique and the correct use of insulin delivery devices. Despite recommendations for a single-use device, the pen needle reuse remains common. This study explored pen needle reuse patterns, reasons for reuse, and motivators to changing reuse behavior, in order to provide actionable insights for clinical education and patient-support interventions.
methodsA cross-sectional online survey was conducted with 500 U.S. adults with type 1 diabetes (T1D) or type 2 diabetes (T2D) who inject insulin at least twice daily using an insulin pen and use insulin pen needles at least twice before replacing.
resultsApproximately 70% of survey participants reported using needles 2-5 times before replacing, and about 30% used them six or more times, with higher reuse among participants with T1D. Despite most participants reporting initial insulin injection education (86.8%), the majority indicated limited follow-up regarding injection practices. Specifically, 73.6% indicated their injection sites were never examined by a healthcare professional (HCP), 72.8% reported their injection technique had never been reviewed, and 66.2% reported their HCP had never asked them about injection site problems. The main reported reasons for needle reuse include convenience (64.2%), habit (46.2%), environmental/waste concern (40.8%), and cost (40.6%). The most motivating educational messages for changing reuse include those around A1c improvement and lipohypertrophy prevention, with the most trusted sources of information being endocrinologists, followed by primary care physicians (PCP), diabetes educators (known in the U.S. as diabetes care and education specialists), and peers.
conclusionsPen needle reuse is widespread and initial education alone is insufficient. Ongoing reinforcement and messaging from trusted HCPs, particularly around A1c and injection-site outcomes, provide a key opportunity to support behavior change.
