The resulting sample size was 154 plots, which were distributed randomly in three strata: high, medium, and low density.
From this dataset the daily mean, as well as minimum and maximum temperatures and the daily mean of cloud cover in all three strata (high, medium, low) are used.
In the highest THM strata, high versus low water intake was also associated with a lowering of risk.
In the low THM strata, high versus low water intake was associated with a significantly lower risk of bladder cancer (OR = 0.36; 95% CI, 0.15 0.83).
The stratification cohort was determined using the patients' self-reported intake of tomato products (i.e., primary source of lycopene) and fish, and patients were randomized within each of the four strata (high or low level for each dietary factor).
The statistical analysis consisted of two steps: First, an optimized prediction score was derived from the derivation dataset with the aim to provide four distinct risk strata: high, moderate risk, low risk and very low risk.
