The independent effects of H. pylori infection (measured at age 3.5 and 6.5 years) on anaemia, haemoglobin level, and red cell indices (measured at age 6.5 years) were determined using multiple logistic and linear regression.
HAZ, WAZ, and WHZ for children up to 60 completed months were generated using the WHO 2006 growth standards while for those aged 5 17 years were determined using the NCHS/WHO reference.
The rate of change in eGFR per year was determined using a simple regression analysis, applied to all estimates of GFR obtained during the follow-up period (10).
Differences in antibiotic resistance between Dhaka and Matlab for each year were determined using χ tests, with P ≤.05 considered to confer statistical significance.
Mortality rates (95% confidence interval) per 100 person-years were determined using Poisson regression modelling by site for different lengths of time pre- and post-HAART and presented graphically.
Follow-up time ranged from two to five years; median follow-up time for the cohort was 3.3 (range 2.6-4.1 2.6-4.1and was determined using the censoring distribution.
The ESV of Dinghai District for each of the three time periods (i.e., 2006, 2012, and the planned year 2020) was determined using the method described below (Costanza et al. 1997b), which has been applied and proven feasible in previous studies (e.g., Li et al. 2010; Estoque and Murayama 2013).
The 10-year survival was determined using revision to an arthroplasty as the endpoint.
The statistical significance of any differences between the 4th and 5th year students was determined using Chi-square.
