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
Precision medical tests play a critical role in tailoring treatment plans to individual patients and optimizing medical resource utilization. This paper establishes a quantitative model to analyze the relationship between the accuracy of a precision medical test and its cost-effectiveness. Two theoretical lower bounds on test accuracy are proposed to be required for a testing strategy to be considered cost-effective. The first bound ensures that the intervention matched to a test result remains locally optimal for the reported patient class, thereby satisfying a local efficiency criterion. The second bound ensures that the testing strategy yields a higher expected net monetary benefit for the entire population compared to no testing, satisfying a global efficiency criterion. A special case analyzing sensitivity and specificity for binary test results illustrates these thresholds intuitively. Numerical simulations support these theoretical findings. The results illustrate how accuracy requirements depend on class prevalence, treatment benefits, and test costs, and may serve as a preliminary screening criterion for further evaluation.
