The maximum acceptable amount of two-wheeled containers collected during an 8-h working day was estimated using the energetic criterion of a maximum oxygen uptake of 30% VO2max.
Cell doubling time (t d, day) was estimated using Eq. (2), while productivity (P, g/L/day) was calculated using Eq. (3) (Sankar et al. 2011): t _{d} left( d right) = frac{ln2}{{mu_{max} }}, (2) P = frac{{X_{t} - X_{0} }}{{t_{t} - t_{0} }}, (3)where 'X t ' is the biomass concentration at time 't', while 'X o' is the initial biomass concentration at inoculation time t o.
The total weight of soil eaten per day was estimated using mean weight of a pemba stick.
The hazard ratio (HR) of pacemaker insertion associated with amiodarone doses >200 mg per day was estimated using a Cox proportional-hazards model including all fixed and time-dependent covariates.
In the case of caregiver costs, the cost and percentage of patients who used a caregiver, including an informal caregiver such as a relative or friend, were estimated from data from the Korea Health Panel study, and the admission day was estimated using NHIC statistics.
Time spent in moderate-to-vigorous physical activity (MVPA) per day was estimated using an intensity threshold of 100 m g based on 5-s epoch data and 10 min bout durations in the minimum, and <20% of the data points below this threshold.
Survival curves up to day 30 were estimated using the Kaplan Meier method, and the log rank (Mantel Cox) test was used to estimate differences among the predefined groups.
Associations between biomarkers and 14-day mortality were estimated using Cox models with multiple imputation (see Supplementary Material).
Standard costs of day-hospital treatment were estimated using annual accounts from the Department of Personality Psychiatry, Oslo University Hospital.
Thirty-day survival curves were estimated using the Kaplan Meier method and their comparison related to genotypes was performed with the log-rank test.
