The Advanced Organ Support (ADVOS) hemodialysis system fulfills its intended purpose: Analysis of data from 282 patients from the Registry on Extracorporeal Multiple Organ Support (EMOS).

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
Several case series have highlighted the ADVOS hemodialysis system's efficacy in eliminating water-soluble and protein-bound substances across diverse patient populations, such as multiorgan failure, acute-on-chronic liver failure (ACLF), acidosis, and even COVID-19. The EMOS-Registry, a non-interventional, multi-center patient registry, amassed real-world evidence, culminating in the largest patient cohort treated with ADVOS to date. This study aims to present and analyze the final performance and safety outcomes from the entire dataset comprising 282 participants. Data spanning from January 18, 2017, to August 31, 2020, were collected from five German hospitals, encompassing subsets of patients with acidosis and ACLF grade 3. Performance and safety were assessed through vital signs, clinical laboratory parameters and blood gas analyses. The SOFA Score-Standardized Mortality Ratio (SMR) served to evaluate patient outcomes in the absence of a control group. Participants, with a median age of 58 years, predominantly male (64%), exhibited a high requirement for mechanical ventilation (68%) and vasopressors (82%) with a median SOFA Score of 15. Notably, a median of 3 (IQR 2, 5) ADVOS sessions per patient were administered. Following the initial treatment, significant reductions were observed in bilirubin (-1.9 [CI 95% -1.3, -2.5]), creatinine (-0.5 [-0.4, -0.6]), and blood urea nitrogen (-13.1 mg/dL [-10.3, -16.0]) levels. Moreover, there were marked improvements in blood pH (7.34 vs. 7.41, p < 0.001), HCO3- (19.4 vs. 24.6 mmol/l, p < 0.001) and base excess (-5.6 vs. 0.2 mmol/l, p < 0.001). The observed mortality rate (66%) was notably lower than the expected rate based on SOFA Score (84%), resulting in a SMR of 0.79 (95% CI: 0.66-0.93), with a calculated number needed to treat (NNT) of 5.8. This study emphasizes the ADVOS system's efficacy in eliminating water-soluble and protein-bound substances and correcting acid-base imbalances across a diverse cohort with multiorgan failure. However, further validation through randomized controlled trials is warranted to solidify these findings.
