Outcomes of thoracic aortic interventions in Marfan syndrome in the state of Texas over 11 years.

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
objectivesMarfan syndrome is a heritable connective tissue disorder with significant aortopathy and conveys substantial cardiovascular morbidity. This study characterizes the mortality and morbidities of thoracic aortic interventions (TAI) in the Marfan syndrome population in the state of Texas from 2009 to 2019.
methodsA retrospective review of the Texas Inpatient Discharge Dataset from 1 January 2009 to 31 December 2019. Discharges from acute care hospitals with a Marfan syndrome diagnosis by the International Classification of Diseases 9/10 codes and a procedure code for TAI were analysed utilizing descriptive, univariate and multivariable regression statistics.
resultsThere were 4641 Marfan syndrome discharges identified, of whom 644 (13.9%) underwent TAI. Thoracic or thoraco-abdominal aortic dissection or rupture was noted in 223 (34.6%). Thirty-three (5.1%) had a concomitant coronary artery intervention. There were 30 (4.7%) in-hospital mortalities, 126 (19.6%) diagnoses of acute renal failure (ARF), 52 (8.1%) had mechanical ventilation >96 h and the median length of stay was 10 [interquartile range (IQR) 7-16] days. After adjustment, concomitant coronary artery intervention was associated with in-hospital mortality [odds ratio (OR) 3.69 [IQR 1.15-11.90], P = 0.029] and ARF (OR 2.66 [IQR 1.19-5.94], P = 0.017). Aortic dissections/ruptures were associated with ARF (OR 1.73 [IQR 1.14-2.63], P = 0.010), ventilation >96 h (OR 2.19 [IQR 1.21-3.97], P = 0.010), and 15% longer length of stay (95% confidence interval 2.4-29.1%, P = 0.038).
conclusionsTAI are frequent among the hospitalized Marfan Syndrome population. Concomitant coronary intervention is associated with increased risk of death and aortic dissections/ruptures are associated with increased morbidity. The high prevalence of aortic dissections/ruptures points to a potential target for improving imaging surveillance, adherence to treatment guidelines and preventative management of Marfan syndrome aortopathy.
