Outcomes of severely impaired renal function patients with and without dialysis following isolated coronary artery surgery - a retrospective cohort study.
Article in Annals of medicine and surgery (2012), 2025. 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
Objectives: Patients with advanced-stage chronic renal failure have poor outcomes following cardiac surgery. Our registry study aimed to compare postoperative and follow-up data between patients who underwent isolated coronary artery surgery with preoperative chronic dialysis and patients with preoperative severe renal impairment who did not require chronic dialysis. Methods: We analyzed 157 948 consecutive adult patients in the Polish National Registry of Cardiac Surgical Procedures (KROK Registry) scheduled for isolated coronary artery surgery between January 2010 and December 2023. Overall, in this cohort, 938 patients underwent chronic dialysis (CD group), and 13 253 patients had severe renal impairment but did not undergo CD (serious renal impairment [SRI] group). Patients in these groups constituted 0.6% and 8.4% of the entire population, respectively. Preoperative data, major postoperative complications, hospital mortality, and mid-term all-cause mortality were compared among patients in CD group and SRI group. Results: Mean age of patients CD group and SRI group was 63.3 ± 9.5 vs. 71.9 ± 8.4 years, respectively ( Conclusion: Patients with CD had higher in-hospital and long-term mortality rates than those with a preoperative SRI. It is possible that the EuroSCORE II underestimates the risk of coronary bypass grafting in a group of patients with chronic dialysis. It is possible that the coagulation disorders may play role in the higher mortality rates in patients undergoing chronic dialysis.
