Non-invasive continuous cardiac output monitoring in thoracic cancer surgery: A comparative study between calibrated pulse contour analysis and chest bioreactance.
Article in European journal of anaesthesiology and intensive care, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04251637 (Non Invasive Cardiac Output Evaluation With Starling SV for Lung Elective Surgery), which is not on this 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.

Abstract
backgroundPatients scheduled for thoracic cancer surgery are eligible for goal-directed fluid therapy, but cardiac output monitoring remains challenging in that specific setting.
objectiveWe aimed to compare cardiac output as measured with chest bioreactance with that measured by calibrated pulse contour analysis; the hypothesis being that both methods would be interchangeable.
designA prospective monocentre observational study.
settingA tertiary university hospital. PATIENTS: Fifty adult patients undergoing thoracic cancer surgery over a one year period.
main outcome measuresSimultaneous measurements of cardiac index (CI) with bioreactance (CI-NICOM) and arterial pulse contour analysis calibrated by transthoracic echocardiography (CI-PCA) were performed at eight pre-specified intra-operative time points and following fluid challenge and/or vasoactive agents. Relationships between absolute values and changes in CI were assessed by linear regression. Interchangeability was tested with Bland-Altman analysis and percentage error calculation. A four quadrant plot was used to evaluate trending ability.
resultsThere was a significant difference between CI-PCA and CI-NICOM: 2.4 ± 0.8 (range: 0.9 to 5.8) l min
conclusionChest bioreactance is feasible and well tolerated in patients undergoing thoracic surgery for cancer. When compared with calibrated PCA over a wide range of CI values, the technique is moderately correlated, not interchangeable, and provides moderate trending ability.
