Is an exercise tolerance test indicated before beginning regular exercise? A decision analysis.
Article in Journal of general internal medicine, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
objectiveThe present study, using a decision analysis, evaluates whether an exercise tolerance test (ETT) is indicated before initiating regular physical activity to reduce the risk of sudden death during exercise training.
designThe study encompasses a decision tree, Monte Carlo simulation, and utility analysis for adults at low to high risk for coronary disease, with a time horizon of five years, with or without routine ETT screening before initiating physical activity. MEASURES: Mortality in Monte Carlo simulation; expected values in utility analysis.
resultsRoutine screening decreases mortality in intermediate to high-risk populations but not in low-risk persons. At all risk levels, the number of exercise-induced deaths prevented is less than the added number of deaths from angiography. Utility analysis indicates inferiority of routine screening, regardless of risk. Personal preferences (perceived stigma from having coronary disease and perceived benefit of regular exercise on quality of life) have a strong influence on the optimal choice.
conclusionRoutine screening before initiating regular exercise is not recommended for the purpose of reducing the risk of sudden death during exercise training.
