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

backgroundFear of pain during insulin injection, using pen injectors, still represents a barrier to diabetes treatment. The development of smaller and thinner needles has improved comfort during the injection, but the influence of other needle geometry features, has been less thoroughly assessed. The aim of this review, is to evaluate the role that pen needle geometry plays in determining patient experience during insulin injection.

methodsA literature search was conducted in PubMed and Scopus to identify the publications assessing the effect of needle geometry and quality on insertion force and pain, experienced by the patient during injection. 22 studies were included in this review. All studies included, at minimum, an evaluation of the perceived injection pain, using a Visual Analogue Scale (VAS).

resultsThe clinical evidence demonstrated that in addition to the pain reduction experienced with increasing needle gauge, other geometrical features such as shorter needle length, thinner wall design, improved tip geometry and coating with lubricant, are associated with reduced injection pain and improved patient experience. Furthermore, it was indicated that the needle features shown to help reduce the experienced pain, would not negatively affect the frequency and intensity of injection related site reactions or needle-related failures, such as breakage and bending.

conclusionsPen needle geometry affects the insulin injection experience of diabetic patients. Increased needle gauge, shorter length, improved tip design and mechanical characteristics of the needle are all associated with a perceived reduction of the pain during insulin injection and an overall improved patient experience.
