Practice Pattern Variability in the Use of Pulmonary Arterial Catheters in Cardiac Surgery.
Observational study in Journal of cardiothoracic and vascular anesthesia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesTo quantify intraoperative pulmonary arterial catheter (PAC) use during cardiac surgery and identify hospital-, anesthesiologist-, and patient-level factors associated with PAC utilization.
designA cross-sectional, observational study using generalized logistic mixed models to examine variations in PAC use.
settingFifty-three US academic hospitals participating in the Multicenter Perioperative Outcomes Group (MPOG) national registry
participants145,343 adult patients undergoing cardiac surgery between January 1, 2016, and December 31, 2022. INTERVENTION(S): Receipt of intraoperative PAC, defined by ≥60 minutes of physiologically plausible pulmonary arterial pressures. MEASUREMENTS & MAIN
resultsThe primary outcome was PAC utilization. Mixed-effects logistic regression quantified fixed-effect predictors, and variation attributable to anesthesiologists and then to anesthesiologists nested within a hospital was characterized using median odds ratio (MOR). Of the 145,343 cardiac surgeries performed across 53 hospitals, 104,626 (72%) included PAC monitoring. PAC use varied widely across hospitals (0-98%) and across anesthesiologists (0-100%). PAC was used most frequently in heart transplants (94%) and lung transplants (87%) and least frequently in pulmonic valve procedures (30%). A patient's likelihood of receiving a PAC was influenced most strongly by hospital (MOR, 15.00; 95% confidence interval [CI], 8.98-28.32), with substantially less variation attributable to an anesthesiologist within the same hospital (MOR, 1.70; 95% CI, 1.61-1.81).
conclusionsIntraoperative PAC monitoring is used in nearly three-quarters of cardiac surgeries at US academic centers, with hospital practice pattern the factor most closely associated with PAC utilization.
