Preoperative renal function affects outcomes of surgery for aortic arch aneurysm in the elderly.
Article in General thoracic and cardiovascular surgery, 2021. 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
objectivesThis study aimed to determine the optimal surgical procedure for arch aneurysm in the elderly based on preoperative comorbidities, especially focusing on renal function.
methodsThe medical records of 374 patients who experienced arch surgery between 2008 and 2019 were reviewed. Among the 374 patients, 92 who underwent total arch replacement (TAR) were assigned to the TAR group and the remaining 152 who underwent debranching thoracic endovascular aortic repair (DTEVAR) were assigned to the DTEVAR group.
resultsChronic kidney disease (CKD) was an independent risk factor of mortality (hazard ratio, 2.85; p = 0.029) in the TAR group but not in the DTEVAR. In the Grade I/II category CKD (estimated glomerular filtration rate (eGFR) > 60 mL/min), freedom from all-cause mortality was significantly higher in the TAR group than in the DTEVAR group (p = 0.0155, log-rank). Freedom from all-cause mortality was comparable between the two groups in the Grade IIIa CKD (eGFR, 45-60) (p = 0.584, log-lank), Grade IIIb (eGFR, 30-45) (p = 0.822), and Grade IV/V (eGFR < 30) (p = 0.548).
conclusionIn elderly patients who underwent TAR, CKD was the independent risk factor of the mortality, but not in the patients who underwent debranching TEVAR. Conversion of surgical strategy from TAR to debranching TEVAR in the treatment of aortic arch aneurysms in the elderly with CKD below Grade IIIa is acceptable considering that less-invasiveness. While, in the elderly with Grade I/II CKD, TAR still remains as a primary choice for the arch repair for better mid-term survival.
