Agreement of the 2020 Brazilian Society of Cardiology cardiac risk stratification protocol in cardiac rehabilitation programs: a cross-sectional study.
Observational study in Revista da Associacao Medica Brasileira (1992), 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
backgroundCardiac risk stratification protocols are widely used in cardiac rehabilitation programs, but divergent classifications limit their applicability. In 2020, the Brazilian Society of Cardiology updated its protocol; however, its agreement with established protocols and inter-rater reliability in cardiac rehabilitation programs remain unclear.
objectiveThe aim of this study was to evaluate the agreement between the 2020 Brazilian Society of Cardiology cardiac risk stratification protocol and protocols used in clinical practice and to assess inter-rater agreement in its application. DESIGN AND
settingCross-sectional observational study conducted in a cardiac rehabilitation program at a public university in Brazil.
methodsMedical records of 51 cardiac rehabilitation programs participants were independently analyzed by two cardiovascular physical therapists using the 2020 Brazilian Society of Cardiology, American Association of Cardiovascular and Pulmonary Rehabilitation, American College of Sports Medicine, Pashkow, and 2013 Brazilian Society of Cardiology protocols. Agreement between protocols and inter-rater reliability was assessed using the Kappa coefficient.
resultsThe 2020 Brazilian Society of Cardiology protocol showed moderate agreement with Pashkow (k=0.544; 95%CI 0.340-0.748; p<0.001) and the 2013 Brazilian Society of Cardiology protocol (k=0.708; 95%CI 0.498-0.918; p<0.001), good-to-excellent agreement with American Association of Cardiovascular and Pulmonary Rehabilitation (k=0.780; 95%CI 0.604-0.956; p<0.001), and weak, nonsignificant agreement with American College of Sports Medicine (k=0.003; 95%CI -0.015 to 0.021 p=0.866). Inter-rater analysis demonstrated excellent agreement between evaluators (k=0.843; 95%CI 0.672-1.014; p<0.001).
conclusionThe findings provide preliminary evidence regarding the agreement and reproducibility of the 2020 Brazilian Society of Cardiology protocol compared with established cardiac rehabilitation programs protocols; however, further studies are needed to evaluate its predictive validity for exercise-related events.
