Incidence and impact of loss of pulsatility on outcomes after extracorporeal cardiopulmonary resuscitation - A retrospective cohort study.
Article in Resuscitation plus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Aim: Loss of pulsatility, defined as zero pulse pressure, can occur following extracorporeal cardiopulmonary resuscitation (ECPR). The aim of this study was to determine the incidence of loss of pulsatility and assess its association with in-hospital mortality in ECPR patients. Methods and Settings: A retrospective cohort study of consecutive ECPR patients admitted between January 2011 and December 2024 to a high volume ECMO centre. Loss of pulsatility was defined as any documented pulse pressure (difference in systolic and diastolic arterial blood pressure) of 0 mmHg during the first 12 h following ECPR. Univariable and multivariable logistic regression models were used to identify association with in-hospital mortality. Results: During the study, 221 ECPR patients - mean age 50(±13.7) years, 165 (75%) males, met the inclusion criteria. At least one episode of loss of pulsatility occurred in 108 patients (49%). The loss of pulsatility group had a higher proportion of out-of-hospital cardiac arrest and longer arrest-to-ECMO time. In-hospital mortality was higher in the loss of pulsatility group (74% vs 48%; Conclusions: Loss of pulsatility is an important predictor of mortality after ECPR. Future studies should elucidate the underlying causes of loss of pulsatility and determine whether strategies to prevent or treat it improve patient outcomes.
