Scientists, it seemed clear, began with careful observations, cautiously proceeded to a tentative hypothesis, progressed to more secure but still provisional theories, and only in the end achieved, after a long process of verification, the security of permanent laws.
However, we make this observation cautiously.
Despite the relatively small sample size, some observations can be cautiously derived from the data.
Again, this observation should be cautiously unravelled, but a possible explanation may be that IL12 is an essential pro-inflammatory cytokine that is decreased in several cancer types, particularly in later stages; hence, it might be in relation to inflammatory and FDG-avid peri-tumoural tissue, the first to be dampened by an active targeted compound (Del Vecchio et al, 2007).
Therefore, each of the above observations should be interpreted cautiously.
These observations should be interpreted cautiously, bearing in mind the limited number of cases in these subgroups.
These observations must be interpreted cautiously, because the analyses were not defined before treatment was started, the period of follow-up was shorter than planned, and the results could have been influenced by many postrandomization factors.
For cancers of the upper gastrointestinal tract, epidemiological studies have generally observed that people with a relatively high intake of fruit and vegetables have a moderately reduced risk, but these observations must be interpreted cautiously because of potential confounding by smoking and alcohol.
However, this observation must be taken cautiously because GH levels were measured only once per mouse.
However, this observation needs to be cautiously interpreted, as although HIF-1 α downregulation was seen in both combined arms, only in Detroit 562 there was decreased angiogenesis.
The odds ratio for freedom from postoperative complications was 9.00 for the high MIF expression genotype, CATT7X, but this observation should be considered cautiously given the small patient cohort and the wide 95% confidence interval (1.14 71.04).
