Since HIV has become a chronic disease with the prospect of long-term survival, examination of the burden of HIV, and comorbid conditions, on health-related quality of life (HRQOL) has become increasingly important (Sherbourne et al., 2000).
We identified factors associated with three colon cancer practice variations potentially linked to better survival: examination of ≥12 lymph nodes (LN), non-use and use of adjuvant chemotherapy for stage II and stage III patients, respectively.
The proportional hazard assumption will be evaluated using log-log survival plots, examination of Schoenfeld residuals, and testing of interactions between variables and time.
To understand if consumption of ethanol by bats alters their access to food and general survival requires examination of behavioural responses to its ingestion, as well as assessment of interspecific variation in those responses.
In the current study, extent of staining was not found to be informative for survival but unbiased examination of survival by intensity of staining was.
The study was retrospective, and the data in the documentation were not complete (including survival rate, histopathological examination, or such information as address).
However, purely hypothetical concerns about the quality of data should not be used as an excuse to dismiss substantial and persistent differences in survival without quantitative examination.
Other researchers have shown correlations between endogenous increase 43 and exogenous application of ABA and proline concentrations in drought-stressed plants, but the relationship between proline and ABA in stress survival requires further examination.
Consider, for example, current CRC screening guidelines, which suggest that the benefit of identifying early-stage CRC (i.e. the increase in 5-year survival) via endoscopic examination in an asymptomatic population with an incidence rate of 0.05% [ 54] outweighs the combined risks of complications from endoscopy and late-stage detection mortality.
Several groups have observed a relationship between the number of lymph nodes identified at pathological examination and survival in colorectal cancer patients, examining usually Dukes' B, or Dukes' B and C patients (Michiels et al, 1994; Caplin et al, 1998; Tepper et al, 2001; Cserni et al, 2002; Goldstein, 2002; Prandi et al, 2002; Swanson et al, 2003; Jestin et al, 2005).
This War of Mine, for instance, tackles sexual violence during war as part of its examination of survival in war zones; games that explore violence, like Spec Ops: The Line, are only possible now because we have begun to accept that games can be for grown-ups and can explore difficult, adult topics intelligently.
