The phrase "a more sensitive index" is correct and usable in written English.
It can be used when discussing a measurement or indicator that is more responsive or reactive to changes in a particular context.
Example: "In our study, we found that a more sensitive index was necessary to accurately capture the fluctuations in patient responses."
Alternatives: "a more responsive measure" or "a more precise indicator."
Thus, eye-movement measures, which sample data continuously, are likely to be a more sensitive index of attention allocation than reaction time.
In conclusion, midwall shortening is a more sensitive index of systolic function in subjects with pressure-overload hypertrophy, and it identifies high-risk patients who may benefit from a more aggressive antihypertensive program.
While the absence of lexical decision priming has already been demonstrated in this design it seems premature to draw any definite conclusions from this purely behavioral result since event related potential (ERP) measures have been shown to be a more sensitive index of semantic activation.
A broader spectrum of community-linked satisfaction indicators may yield a more sensitive index to reflect community behaviours, interaction, satisfaction and/or attitudes towards urban lake ecosystems.
Renograms proved to be highly variable in mice, such that we decided to test the FUR quantitative approach, which provided a more sensitive index of the extent of renal failure at day 65.
Compared with BSI, SUV seems to be a more sensitive index with a wider dynamic range, reflecting osteoblastic activity for each skeletal lesion with a suitable threshold; this is because SUV was derived from precise 3-dimensional data, while BSI was derived from 2-dimensional data.
Da Silva and coworkers [ 67] suggested that CRP might be a more sensitive indicator of sepsis than leukocyte indices alone.
Net relatedness index reflects the more general structure, whereas NTI is a more sensitive indicator of phylogenetic extendability or segregation among components.
We preferred to use WC over WHR as WC is more sensitive index of upper body adiposity than WHR in Indian population [ 15].
Second, our findings demonstrate that hierarchy recall accuracy, but not awareness scores, was a significant predictor of inferential performance across the entire group of participants—suggesting that this measure may be the more sensitive index of relational hierarchy knowledge.
The recording of electroencephalographic (EEG) activity during response inhibition has been suggested to yield more sensitive indices (i.e., event-related potentials, ERPs) of response inhibition and may therefore clarify the inconsistent results.
