Efficacy and safety of different doses of ligelizumab in patients with chronic spontaneous urticaria: a systematic review and meta-analysis of randomized controlled trials with GRADE evaluation.

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
backgroundChronic spontaneous urticaria (CSU) is a skin condition characterized by itchy hives and/or angioedema, impairing patients' quality of life even with the current available medications. This study aims to evaluate the efficacy and safety of Ligelizumab, a high-affinity monoclonal anti-IgE antibody, in the treatment of CSU.
methodsWe performed a systematic review and meta-analysis in accordance with PRISMA criteria, methodically exploring databases for randomized controlled trials (RCTs) comparing Ligelizumab with placebo in patients with CSU. Studies that reported outcomes like the itch severity score (ISS7), the hives severity score (HSS7), and adverse events were included in our analysis.
resultsFour RCTs were included in our analysis with a total of 2,481 patients with CSU. Ligelizumab significantly improved urticaria symptoms as measured by change in ISS7 at week 12 in adults (MD = -3.67, 95% CI: [-4.25 to -3.09], p < 0.00001), change in UAS7 at week 12 in adults (MD = -9.18, 95% CI: [-10.45 to -7.92], p < 0.00001), and change in UAS7 at week 12 in adolescents (MD = -6.48, 95% CI: [-12.84 to -0.12], p = 0.05). Regarding safety outcomes, only Ligelizumab 120mg showed significantly higher upper respiratory tract infection rates (RR = 2.70, 95% CI [1.17 to 6.21], p = 0.02).
conclusionOur findings suggest that Ligelizumab, at doses 72 and 120 mg, might be able to improve the symptoms of CSU evidenced by the improvements in ISS7 UAS7 and UAS7 response rate and the overall quality of life with an acceptable safety profile with certain concerns regarding Ligelizumab 120 mg causing upper respiratory tract infections. However, the small number of studies included limit the generalizability of our results.
