The choice of analysis to demonstrate hotspots at every scale is unusual in the sense of involving a correlation between two quantities and how this changes with resolution.
Hence our conclusion of spatial clustering at every scale does not depend only on the inverse correlation between age and MPF, but on two further analyses (i.e., the demonstration of hotspots within hotspots in Figure 2, and the semivariogram shown in Figure 2 figure supplement 1), which do not involve a correlation between two variables.
Inter-hemispheric coupling also has been observed, which involves a high correlation between the onset of the Antarctic PMC season and the time of breakdown of the stratospheric winter vortex.
Although it cannot be stated that MTHFR is the target gene of the chromosomal loss involving the 1p36.3 region, a correlation between loss of heterozygosity at this locus and decrease in MTHFR activity was shown, suggesting a role of these allelic deletions in generating a biochemical defect in folate metabolism.
In many species, softening during early ripening does not appear to involve pectin depolymerisation, but a correlation between PG gene expression and softening rate, together with QTL analysis, has consistently implied some involvement of PG in the softening and textural change of fleshy fruit, principally during late ripening [ 4, 11- 21].
Regardless of the mechanisms involved, the present study clearly demonstrated a correlation between the use of MSCs with superior tissue repair, which will require further investigations if we wish to elicit the mechanisms involved.
Due to the limited knowledge of gene functions it remains elusive at present, whether there is a correlation between excess of genes involved in melanin synthesis and the vast diversity of coloration in fish.
The analysis of results involves the correlation between the overtopping energy transfer with the relative wall height and the relationship between wave run-up and overtopping rate.
Endogeneity involves possible correlation between interviewee recall of program exposure and some other unobserved determinants of modern contraceptive use that were not measured in the surveys, with the potential result that estimates of the impact of recall on modern contraceptive use will be biased.
