Real life use of ravulizumab in Italian patients with paroxysmal nocturnal hemoglobinuria: evidence from the REACTION observational study.
Observational study in Annals of hematology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05274633 (Real Life Use of Ravulizumab in Italian Patients With Paroxysmal Nocturnal Hemoglobinuria a Multicenter Observational Retrospective and Prospective Cohort Study.), which is not on this map.

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.

Abstract
Ravulizumab is a second-generation C5i engineered from eculizumab to achieve immediate, complete, and sustained inhibition of terminal complement activity in PNH. The REACTION observational cohort study describes the effectiveness and tolerability of ravulizumab in Italian patients who were previously treated with eculizumab. Eighty-one PNH patients were enrolled in this study. The primary endpoint was the percentage change in lactate dehydrogenase (LDH) from baseline to the end of observation (52 weeks follow-up). Among secondary endpoints, transfusion avoidance, breakthrough hemolysis (BTH) and patients' quality of life (QoL) were evaluated. The median (25-75 percentiles) percentage change in LDH at 52 weeks follow-up was -2.6 (-11.5-13.4) U/L, with 92.3% of the patients presenting LDH within or < 1.5 × upper limit of normal (ULN). Overall, 20 (25.0%) patients required transfusion during the eculizumab period and 15 (18.8%) during the ravulizumab. Seven BTH events were observed, 5 during eculizumab period and 2 (triggered by other medical conditions) during ravulizumab, suggesting the reduction of pharmacokinetic BTH during ravulizumab treatment. EORTC-QLQ-C30 and FACIT-Fatigue scores were similar to the general population, and patients' preference indicated ravulizumab as the favorite treatment. The REACTION study confirmed the effectiveness of ravulizumab in maintaining stable disease and hemolysis control in the real-world setting. Clinical trial registration. NCT05274633, 02-Mar-2022.
