Further, the proportion of exposed follow-up time at risk is obtained through the question of usual frequency multiplied with the hazard period.

Responding neurons display a significantly higher average basal firing rate than that of non-responders [12], and thus, to optimize the discrimination between the two populations, the 5-HT neurons selected for recordings had been chosen for discharging within either the lower (≤1 Hz) or the upper (≥2 Hz) range of usual frequencies.
At baseline, participants completed a 124-item food frequency questionnaire (FFQ, developed at the US NCI) on usual frequency of food and beverage consumption (10 categories) and usual portion size (3 categories) over the past year.
For the taste test, participants were asked to complete a 2 page questionnaire (based on Houben, 2011) with open-ended questions asking how they would describe various different aspects of the two foods (such as sweetness, saltiness and taste), along with Likert scales measuring palatability of the two foods (on a scale of 1 10) and usual frequency of consumption.
The index demonstrated anticipated associations with self-reported quality of life, activities of daily living, WOMAC functional status score, use of walking support, frequency of usual exercise, frequency of falls and dependence upon another person for assistance with chores.
We had information from the enrollment questionnaire on potential confounders identified from previous literature: age, state, education, marital status, number of children in family, usual frequency of alcohol consumption per week in the past year, cigarette smoking, diabetes (an indication of chronic disease), farm size, and wearing chemical-resistant gloves when personally handling pesticides.
To examine the robustness of the exact calculation, we also calculated the expected odds of exposure using self-reported usual frequency of trigger exposure according to the standard case-crossover methodology and applied three different estimations of the time at risk leading to four alternative analytical strategies (B-E in Table 2) [ 18].
The FFQ contains questions on the usual frequency of consumption of 77 main food items during the year preceding enrollment.
Self-administered food-frequency items on the questionnaires asked participants to report usual frequency of consumption of 96 items over the previous year.
The questionnaire assesses usual frequency of consumption of 126 foods (on a scale ranging from never to ≥ 2 times per day) and supplements (no/yes, plus the amount).
The FFQ asks about the usual frequency of consumption of 212 food and beverage items, excluding alcohol, and how their usual serve (portion) compared to a standard serve size given in household measurements (spoons, cups, slices, etc).

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
