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
This study retrospectively analyzed data from 25 patients with paroxysmal nocturnal hemoglobinuria (PNH) admitted to Peking Union Medical College Hospital and Dongfang Hospital of Beijing University of Chinese Medicine from January 2023 to June 2024. Patients receiving sufficient eculizumab treatment for at least 3 months and who completed hemolytic complex (CH50) level testing pre- and post-treatment for 3 and 6 months were selected. Blood routine, biochemistry, and the 50% CH50-related indicators were monitored pre- and post-treatment. Among these patients, 24 completed 6 months of treatment and CH50 testing. After 3 and 6 months of eculizumab treatment, all patients with PNH showed significant improvement in symptoms, with lactate dehydrogenase (LDH) levels decreasing from a baseline of (1 814.4 ± 924.8) U/L to (248.5 ± 61.0) U/L and (239.3 ± 44.8) U/L. Hemoglobin levels increased from a baseline of (73.9±14.4) g/L to (99.9 ± 21.3) g/L and (99.6 ± 19.8) g/L. The baseline CH50 level was (32.4±14.7) %, which decreased to 2.0% (1.0% -8.0% ) and 1.0% (1.0% -4.0% ) at 3 and 6 months posttreatment, respectively. At baseline, a linear correlation was found between CH50 and LDH levels (
