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
introductionHereditary angioedema due to C1 inhibitor deficiency (HAE-C1INH) has a substantial impact on patients' health-related quality of life (HRQoL). While generic instruments are frequently used for assessment, they may not fully capture the disease-specific burden. This study aimed to evaluate HRQoL in patients with HAE-C1INH types I and II using validated, angioedema-specific tools. The aims of the study were to assess HRQoL and disease control in patients with HAE-C1INH using validated angioedema-specific tools and secondarily to explore the association between attack localization and domain-specific quality-of-life impairments.
methodsIn this multicenter cross-sectional study, 82 patients with HAE-C1INH from six referral centers completed the Angioedema Control Test (AECT), Angioedema Activity Score (AAS)-28, and Angioedema Quality of Life questionnaire (AE-QoL). Family screening was conducted among those who consented.
resultsPatients experiencing attacks in the extremities (p < 0.001) and laryngeal/pharyngeal regions (p = 0.028) had significantly lower AECT scores, indicating poorer disease control. Higher AAS-28 scores were associated with attacks in the extremities (p = 0.008), abdomen (p = 0.018), face/neck (p = 0.004), larynx/pharynx (p < 0.001), and tongue/uvula/palate (p < 0.001). AE-QoL scores revealed impaired quality of life across all attack locations. Subdomain analysis showed that abdominal attacks significantly impacted the functioning (p = 0.005) and food (p = 0.037) domains. Attacks involving the face/neck and larynx/pharynx were associated with substantial impairment in fatigue/mood (p = 0.002, p = 0.003), functioning (p = 0.044, p = 0.002), and fears/shame (p = 0.039, p = 0.005) subdomains.
conclusionWhile attack frequency and disease control remain the primary determinants of HRQoL in HAE-C1INH, our findings indicate that attack localization is associated with distinct domain-specific quality-of-life impairments. Beyond assessing attack frequency, the use of disease-specific QoL tools allows for the identification of domain-specific impairments. Personalized treatment strategies targeting both symptom control and quality-of-life domains are essential for alleviating the long-term burden on patients and their families.
