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
Introduction: In the majority of patients with hereditary angioedema (HAE) due to C1-inhibitor deficiency (HAE-C1INH), effective long-term prophylactic (LTP) treatment can achieve complete disease control. Lanadelumab is one of the first-line option recommended for this purpose. Our study aimed to evaluate changes in disease control, quality of life, and attack frequency among Romanian HAE-C1INH patients, during the first year of treatment with lanadelumab. Methods: This non-interventional prospective study included the Romanian HAE-C1INH patients enrolled in the first year of the national lanadelumab treatment program. Angioedema Control Test, (AECT), Angioedema Quality of Life Questionnaire (AE-QoL) and attacks frequency were recorded at baseline and at 3, 6, 9 and 12 months. Results: Twenty-four patients (14 women [58.3%], 10 men [41.7%]) initiated lanadelumab therapy, with a mean age of 40.7 years. Most had HAE-C1INH type I (22 patients, 91.7%), and one patient was under 18 years of age. Ten patients switched from LTP with intravenous plasma-derived C1-INH, while 14 were previously managed with on-demand therapy only. Baseline scores were: AECT 4.5 [interquartile range (IQR) 2.0], AE-QoL 66.1 [standard deviation (SD) 18.3], and a mean attack frequency of 10.0 (IQR 4.0) (over the preceding three months). Improvements were observed at each follow-up point, with respective scores at 3, 6, 9 and 12 months as follows: three months: AECT 12.0 (IQR 5.8) / AE-QoL 35.3 (SD 23.2)/ attacks 3.4 (IQR 5.0); six months: AECT 12.3 (IQR 5.3) / AE-QoL 35.4 (SD 25.4)/ attacks 2.8 (IQR 4.8); nine months: AECT 12.6 (IQR 5.8) / AE-QoL 34.1 (SD 23.2)/ attacks 2.2 (IQR 3.8) and 12 months: AECT 12.9 (IQR 5.5) / AE-QoL 32.1 (SD 21.6) / attacks 1.4 (IQR 2.0). Seven patients became symptom-free after the first dose, and four more achieved this status within the first three months. Discussion: LTP with lanadelumab provided effective disease control and significantly improved quality of life in patients with HAE-C1INH over the course of one year. Regular evaluations at relatively short intervals by the availability and ease of administration of validated questionnaires serve as a useful tool for clinicians in the comprehensive assessment of HAE patients and offer a valuable means of monitoring treatment effectiveness.
