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
Background: Hypotension frequently occurs in patients who are undergoing plasma exchange procedures. However, the prevalence, clinical manifestations, and determinants of hypotension during plasma exchange in patients with neuroimmunological disorders have not been fully elucidated. The aim of this retrospective cohort study was to evaluate the current status and influencing factors of hypotension during plasma exchange in patients with neuroimmunological diseases, to provide insights for clinical care. Methods: This study encompasses patients diagnosed with neuroimmunological disorders who received plasma exchange treatment at a tertiary hospital in Nanjing, China, over a period from February 1, 2023, to April 30, 2024. The demographic characteristics and clinical profiles of these patients were subjected to a comprehensive analysis. To ascertain the factors influencing the development of hypotension during plasma exchange, a logistic regression analysis was performed. Results: A total of 206 patients with neuroimmunological diseases were included, the incidence of hypotension during plasma exchange in patients with neuroimmunological diseases was 33.01% (68/206). There were statistical differences in the age, use of sedative drugs during plasma exchange, pre-plasma exchange systolic blood pressure and serum calcium between hypotension and control group. Logistic regression analysis indicated that age [odds ratio (OR) =2.851, 95% confidence interval (CI): 1.978-3.194], use of sedative drugs during plasma exchange (OR =3.175, 95% CI: 2.363-4.425), pre-plasma exchange systolic blood pressure (OR =0.857, 95% CI: 0.410-0.932), and serum calcium (OR =0.791, 95% CI: 0.340-0.895) were the influencing factors of hypotension during plasma exchange in patients with neuroimmune diseases. Conclusions: The incidence of hypotension during plasma exchange in patients with neuroimmune diseases is relatively high. Health care providers should actively take measures against factors associated with hypotension to reduce its occurrence during plasma exchange.
