As an example of how implausible this assumption is, consider that using either "city" or "cities" became 40% proportionally less common in American books between 1800 and 2000, while using any of "farm/s," "rural," and "countryside" became 67% more common, exactly the opposite of what Greenfield might expect given the shift in population.
Antibiotic resistance emerged at a greater rate in Enterococcus faecium than in other enterococcal species, and E. faecium isolates became proportionally more common over time.
Acquired causes, however, are proportionally less common than hereditary causes (Connolly, 2001; Wilmshurst et al., 2003).
SP was proportionally more common in MDS/MPD groups combined as compared with CML patients.
Overall, AIDS and death were proportionally more common in non-injectors compared with PWID.
Excessive alcohol use, overweight and underweight patients, and smokers were also proportionally more common among cases than controls.
Although axonal forms are proportionally less common, early onset neuropathies cannot be restricted to demyelinating neuropathies alone.
All substances were proportionally more common among males than among females, but only opiates (p <.02) and cannabis (p <.009) were significant.
Although such correction and adjustment are appropriate on the null hypothesis of no associations genome-wide, it may penalize large genes excessively if true (causative) associations are proportionally more common in smaller genes.
Despite the low incidence of male breast carcinomas overall, the SEER data showed that NEC was proportionally more common in men than IMC-NOS (2.1% of all NEC; 0.8% of all IMC-NOS).
