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

purposeAdherence to recombinant human growth hormone (r-hGH) is critical to growth and other outcomes in patients with growth disorders, but the requirement for daily injections means that ease of use is an important factor. This study assessed the perceived ease of use and functionality of the prototype of a reusable pen injector (pen device) for r-hGH that incorporates several advanced features. PARTICIPANTS AND

methodsSemi-structured 60-minute qualitative interviews were conducted in 5 countries with 57 health care professionals (HCPs) and 30 patients with GH deficiency/caregivers administering r-hGH to patients, including children. HCPs had to be responsible for training in the use of r-hGH pen devices and to see ≥4 r-hGH patients/caregivers per month. Patients/caregivers had to have experience with r-hGH administration for at least 6 months.

resultsThirty-seven (65%) of HCPs described the pen device as "simple" or "easy" to use. The aluminum body was generally perceived as attractive, high quality and comfortable to hold and operate. The ease of preparation and use made it suitable for both children and adults. The ability to dial back the r-hGH dose, if entered incorrectly, was mentioned as a major benefit, because other devices need several user steps to reset. Patients/caregivers felt the pen device was easy to use and the injection-feedback features reassured them that the full dose had been given. Overall, 40 (70%) HCPs and 16 (52%) patients/caregivers were likely to recommend or request the pen device. Moreover, patients/caregivers rated the pen device higher than their current reusable pens and almost equal to the leading disposable device for ease of learning, preparation, administration and ease of use.

conclusionThe prototype pen device successfully met its design objectives and was very well accepted by HCPs and patients/caregivers for its ease of use, appearance and functionality.
