Association of Renal Impairment Severity with Surgical Outcomes in Patients with Infective Endocarditis.
Article in Current cardiology reviews, 2026. 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
introductionThis study aimed to assess the association of renal impairment (RI) severity on short and mid-term outcomes in patients undergoing cardiac surgery for infective endocarditis (IE).
methodsPatients undergoing cardiac surgery for IE between January 2010 and October 2022 were included. They were stratified based on preoperative renal function into four groups: Normal (N: Creatinine clearance (CrCl) >85 mL/min), moderate RI (M: CrCl 51-85 mL/min), severe RI (S: CrCl ≤50 mL/min), and haemodialysis-dependent (H). Each group was compared with group N. Survival analysis was performed using Kaplan-Meier curves. RESULTS AND DISCUSSION: A total of 487 patients (N: 198; M: 154; S: 96; H: 39) were included. Mean age 55.92 ± 14.60 years, 375 (77%) males. Groups M, S, and H vs N demonstrated more atrial fibrillation [17 (11.0%), 20 (20.8%), 6 (15.4%) vs 8 (4.0%); p<0.05]. Groups S and H vs. N had increased incidence of left ventricular ejection fraction <50% [43 (44.8%), 22 (56.4%) vs 43 (21.7%); p<0.001] and preoperative cardiogenic shock [16 (16.7%), 13 (33.3%) vs 9 (4.5%); p<0.001]. The need for postoperative haemodialysis was 21 (13.6%) in M and 23 (23.0%) in S vs. 13 (6.6%) in N (p<0.05). In-hospital mortality was 13 (8.4%), 21 (21.9%), and 11 (28.2%) vs. 12 (6.1%) (p=0.388, <0.001, <0.001), and mortality at a mean of 69.1months was 49 (31.8%), 46 (46.9%), 30 (76.9%) vs. 49 (24.7%) (p=0.142, <0.001, <0.001) in groups M, S, H vs. N, respectively.
conclusionsThe incidence of renal impairment in patients with IE undergoing surgery remains high. Early and mid-term outcomes of those with severe RI and haemodialysis dependence are significantly worse.
