Example: "The study found a much higher correlation between exercise frequency and overall health compared to diet alone."
Alternatives: "a significantly stronger correlation" or "a considerably greater correlation".
Although EGFR overexpression correlated with the 13th pN factor (P = 0.036), a much higher correlation of EGFR overexpression was found with open surgery patients than with laparoscopic surgery patients (P = 0.0063), where laparoscopic surgery was indicative of patients with lower clinical T (definitely clinical T1 or T2).
For instance, even though AuditoryAudVO could match the pattern defined for Entity, it has a much higher correlation to the pattern defined for AuditEntity and hence it is assigned to the AuditEntity component.
In addition, the experimental results also indicate that the red-edge band in WV2 was the worst on estimating LAI among WV2 MS bands and the WV2 MS bands in the visible range had a much higher correlation with ground measured LAI than that red-edge and NIR bands did.
Since the 2008 financial crisis, there's been a much higher correlation between asset classes.
A more accurate depiction of the data would have shown significantly higher volatility, significantly lower risk-adjusted returns, and a much higher correlation to stocks and bonds.
However, DSP showed a much higher correlation with pulmonary function parameters than did 6MWD alone.
However, we have also shown how different the EEJ-Sq relationship is from the total current-Sq relationship, with the latter having a generally much higher correlation.
Although expression level of transcripts and their corresponding proteins may not always correlate during earlier stages of ripening, much higher correlation was observed during the later stages of ripening, indicating complex posttranscriptional control at the onset and early stages of ripening.
They also argued that measures that are based on the impulse response (when available), like the Clarity measure (C50) [1], showed much higher correlation with the tests.
Read frequencies exhibited much higher correlation coefficients in pair wise sample comparisons (r2 = 0.93 0.99) than array hybridization (r2 = 0.83 0.88; Fig. 5 and 6).
Linear regression plots (Figure 3) of undifferentiated ES cells demonstrated much higher correlation to the EB stage (r = 0.91) than to the OL sage (r = 0.70).
