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
backgroundTrypanophobia or "needle phobia" represents a potential hindrance to the effective management of chronic diseases whenever an injectable therapy might be required, especially in case of frequent administrations. Psoriasis, a chronic dermatologic disease, can be effectively treated with biologic drugs administered subcutaneously. Thankfully, anti-IL-23 drugs require few administrations per year and are available in prefilled pens that hide the needle, thus representing a convenient option in patients with trypanophobia.
methodsAn observational multicentric study was conducted on patients with moderate-to-severe psoriasis who were treated with 75 mg × 2 risankizumab prefilled syringe therapy for more than 6 months and reported a loss of efficacy measured by the Psoriasis Area and Severity Index (PASI) from PASI 90 to PASI 75 attributed to a reduction of adherence due to trypanophobia. The patients were switched to 1 prefilled pen of risankizumab 150 mg and asked to fill out the Self-Injection Assessment Questionnaire (SIAQ) before and after the injection at week 0 and at the following administration after 12 weeks. Subjects scored each item of the SIAQ on a 5-point scale, scores were later transformed from 0 (worst experience) to 10 (best experience).
resultsTwenty-two patients were enrolled. The mean SIAQ predose domain scores were 5.5 for feelings about injection, 6.2 for self-confidence, and 6.4 for satisfaction with self-injection. After dose scores were higher (> 8.5) for each of the six domains at Week 0 and even higher after 12 weeks (> 9.0).
conclusionsUser-friendly devices, such as prefilled pens, and a lower number of injections improved patient satisfaction in a group of patients with psoriasis on treatment with biologic drugs. We believe that treatment adherence could be positively influenced by such changes in the way of administration of a biologic treatment.
