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
backgroundDaily therapeutic plasma exchange (TPE) is the cornerstone of treatment for immune-mediated thrombotic thrombocytopenic purpura (iTTP). However, TPE is not a risk-free procedure and there is scarce evidence regarding its safety in iTTP. This study aims to describe the TPE-related clinical complications occurred in a cohort of patients hospitalized for an acute iTTP episode. MATERIALS AND
methodsIn this cross-sectional study, patients hospitalized for an acute iTTP episode at the Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico (Milan) between January 2016 and April 2022 undergoing a central venous catheter (CVC) placement to start TPE were enrolled.
resultsThirty-three iTTP episodes from 32 patients were included, 20 (61%) first episodes and 2 (6%) complicated with acute exacerbations. Twenty-one episodes (64%) were complicated with at least one major TPE-related complication, 18 (55%) with at least one CVC-related complication, of which 9 (27%) with a major complication. Among major CVC-related complications, 5 were venous thromboses (VTs) requiring heparin treatment and CVC removal, and 3 infections (2 systemic) requiring systemic antibiotic treatment and CVC removal. The 19 CVC-related bleeds (in 16 episodes) were minor bleeds and required only local hemostatic medications. Among the major procedure-related complications, the most common were allergic reactions (present in 16 episodes, 49%), mostly urticarial rashes requiring systemic steroids and antihistamines, and clinical hypocalcemia (in 8 episodes, 24%). The episodes complicated with CVC-related VT or infection required a longer hospitalization and those complicated with CVC-related infection required also a higher number of TPE procedures. DISCUSSION: TPE procedure was well tolerated in our cohort of acute iTTP patients in the majority of cases, with CVC-related minor bleeds and allergic reactions being the most common complications. The occurrence of CVC-related major complications, as VT or infections, was associated with a longer hospitalization (medians: 30 vs 11.5 days).
