Benign categorization

Before an opinion regarding test superiority can be made, the source of the data in Table 15-1 should be considered. In particular, it is appropriate to examine the populations studied and the criteria used for diagnosis. The spectrum concerns the medical characteristics of the patients who are involved in the test evaluation. Important aspects include the duration and severity of the disease state, its specific pathological categorization, and the existence of conditions that may affect test performance. Does the study population contain patients typical of those likely to be tested for the disease in question If the selection criteria make patients with prostatitis or benign prostatic hypertrophy (BPH) more or less likely in the study population than the population to be tested in routine use, the test s interpretation must be qualified by this information. 

Although the categorization of substances into those that interact with SH groups and those that can break S-S linkages accommodates many potent irritants, it leaves out those thousands of substances that can act as mild irritants. Indeed, virtually any odorous substance, even if benign at concentrations most commonly encountered, can evoke pungency at high concentrations. 

There are various causes of urinary tract obstruction, which are either benign or malignant and can be further categorized based upon the site of obstruction, be it at the pelviureteric junction (PUJ), along the length of the ureter, or at the vesicoureteric junction (VUJ). 

Here, hazard identification is critical, because a single event may be benign, but cumulative or combinational effects may lead to a major incident. Consequence analysis reveals the effect of various incident outcomes. The likelihood of initiating incidents is estimated in likelihood analysis. Then, it is a question of risk interest, so it is necessary to categorize the risks as discussed in the previous clause, because one may be interested in finding human fatalities or injuries while others may be interested in loss of assets.
