Benoit and McNutt (2003) analyzed duration times and amplitudes of volcanic tremors and followed exponential rather than power-law scaling.
Very few studies have analyzed duration of symptoms in a confounder-adjusted setting, and only as a categorical variable.
In addition, several studies analyzed duration of exposure to TCDD, time since first exposure, and some quantitative or semiquantitative indices of exposure.
Figure 5c,d represents the occurrence rate distributions of the harmonic waves in the analyzed period, which are derived from dividing the total durations of the waves with harmonics (as shown in Figure 5a,b, respectively) by the total analyzed durations in each bin.
Although women from that study also are included in the present analysis, we have expanded on the approach by taking passive smoke exposure into account, rigorously analyzing duration since quitting, adjusting for additional confounders, and also have 16 additional years of follow-up.
However, when analyzing duration of symptoms separately EPV showed that in a patient where not being herself/himself for the preceding period of >1 months and ≤3 months growth of E. coli was with 96% (51-100%) probability associated to this symptom.
The data analyzed were duration of PICU stay, hospital stay, oxygen therapy requirement, duration of oxygen therapy and their relationship to fluid balance on restrictive fluid regimen.
Furthermore, when analyzed with duration of prostitution, no difference for KSHV seroprevalence was detected across different durations of prostitution (Chi sqaure trend =0.326, P = 0.747).
Other clinical variables collected and analyzed included duration of cardiopulmonary bypass (minutes), age, gender, and length of stay (ICU and hospital).
The clinical data was analyzed for duration of symptoms, size of ulcer, location, depth of infiltrates, presence of perforation, thinning, anterior chamber infiltration and duration of treatment.
When the prevalence of biochemical B12 deficiency among those with diabetes taking metformin was analyzed by duration of metformin therapy, there was no notable increase in the prevalence of biochemical B12 deficiency as the duration of metformin use increased.
