The same results were obtained using the success rate as an index of performance.

Comparisons of patient experiences between providers are increasingly used as an index of performance.
The area under the maximum likelihood-estimated binormal ROC curve (AUC) was used as an index of performance.
Although NRMP result analysis and outcomes can be used to establish a rank/match ratio as an index of performance in attracting highly-qualified applicants to the program, this metric is subject to manipulation (residents can be ranked on their likelihood to choose the program, rather than on their desirability).
We recorded the Go success rate, Stop success rate, reaction time (RT) of Go success trials, the stop signal reaction time (SSRT), as well as the effect size of post-error slowing (i.e., how much participants slowed down in a Go trial following a Stop error), as an index of performance monitoring.
Consequently, three indices of performance may be described: oVO2/nVO2 is an index of global performance, with a value below 1 indicating shock; oDO2/nDO2 is an index of circulatory performance, with a value below 1 indicating circulatory failure; and oEO2/nEO2 is an index of tissue performance, with a value below 1 indicating tissue failure.
Reported behavioral data include the signal-detection measure d' as an index of detection performance.
The continuous outputs were used to compute the AUC metrics, and the AUC scores were used as an index of classification performance because they are robust to class imbalances and are better able to incorporate the relationship between probabilistic classifier output and discrete category membership.
Make reviews not just an index of your performance but also a key component of your strategy.
Consequently this is also an index of the performance gap between the two MCP frameworks.
