Impact of acute kidney injury on clinical and functional outcomes in patients undergoing coronary artery bypass grafting: a prospective cohort study.
Article in Jornal brasileiro de nefrologia. 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
introductionAcute kidney injury (AKI) is a common complication after coronary artery bypass grafting (CABG), associated with worse clinical outcomes. However, its impact on functional outcomes remains uncertain.
objectiveTo evaluate the clinical and functional outcomes of patients undergoing cardiac surgery who developed AKI during hospitalization.
methodsA prospective cohort study was conducted with 60 patients evaluated preoperatively, at ICU discharge and at hospital discharge. Clinical and functional variables were collected, including the six-minute walk test (6MWT), sit-to-stand test (STS), Timed Up and Go (TUG), peripheral muscle strength, and the functional independence measure (FIM). Patients were divided into two groups: those with and those without AKI.
resultsFifteen patients (25%) developed AKI. There was no significant difference in ICU length of stay between groups; however, hospital stay was longer in the AKI group (14 ± 5 vs. 9 ± 3 days), and mortality was higher. Patients with AKI showed a 33.53% reduction in the 6MWT distance at ICU discharge, with partial recovery by the time of hospital discharge. In the STS test, patients without AKI performed better at hospital discharge. In the TUG test, AKI patients showed better performance at discharge compared to those without AKI. FIM scores were lower in the AKI group, indicating reduced functional independence.
conclusionPatients with AKI presented worse clinical outcomes and lower functional independence, although they demonstrated potential for functional recovery by the time of hospital discharge, highlighting the importance of postoperative rehabilitation.
