Rapid urbanization has led to a growing sanitation crisis in urban areas of Bangladesh and potential exposure fecal contamination the environment due inadequate poor sludge management. Limited data are available on environmental associated with different pathways Dhaka. We conducted cross-sectional study explore magnitude low-income, high-income, transient/floating neighborhoods Ten samples were collected from each 10 compartments (4 4 high-income 2 neighborhoods). These 1,000 analyzed...
Generalized estimating equation (GEE) is a popular approach for analyzing correlated binary data. However, the problems of separation in GEE are still unknown. The created by covariate often occurs small data and even large with rare outcome and/or high intra-cluster correlation number influential covariates. This paper investigated consequences addressed them introducing penalized GEE, termed as PGEE. PGEE obtained adding Firth-type penalty term, which was originally proposed generalized...
IntroductionMen are vulnerable to ambient heat-related kidney disease burden, but limited evidence exists on how women when exposed high heat. We evaluated the sex-specific association between temperature and urine electrolytes (concentration 24-hour excretion), total protein, volume.MethodsWe pooled a longitudinal data of 1,175 participants' concentration excretion other biomarkers (24-hour protein volume) (5624 person-visits) collected in southwest coastal Bangladesh (Khulna, Satkhira,...
In clinical research, prediction models for binary data are frequently developed in logistic regression framework to predict the risk of patient’s health status such as death and illness. However, when outcome is rare, maximum likelihood (ML) based standard has been reported show poor predictive performance by providing overfitted model. To overcome this, penalized (PML) being widely used prediction, however, their validation settings not well-documented. Several approaches, namely...
Abstract Background Supply driven programs that are not closely connected to community demand and demand-driven fail ensure supply both risk worsening inequity. Understanding patterns of uptake behaviors among the poorest under ideal experimental conditions, such as those an efficacy trial, can help identify strategies could be strengthened in routine programmatic conditions for more equitable uptake. WASH Benefits Bangladesh was a randomized controlled trial provided free-of cost hardware...

Abstract Within epidemiological research, estimating treatment effects from observational data presents notable challenges. Targeted Maximum Likelihood Estimation (TMLE) emerges as a robust method, addressing these challenges by accurately modeling effects. This approach uniquely combines the precision of correctly specified models with versatility data-adaptive, flexible machine learning algorithms. Despite its effectiveness, TMLE’s integration complex algorithms can introduce bias and...
Separation or monotone likelihood can be observed in fitting process of both Poisson generalized (GP) regression, particularly case small and/or sparse count data, using maximum estimation (MLE) when one more regression coefficients diverge to infinity. The study investigates the consequence separation MLE based standard GP model and addressed problems by introducing a penalized approach. function is derived adding penalty term function, which was originally proposed Firth (1993 Firth, D....
ABSTRACT Managed aquifer recharge (MAR), a hydro-geological intervention designed to dilute groundwater salinity, pumps pond water treated through slow sand filter into the underground aquifers. We evaluated microbiological safety of resulting MAR at sites from three districts in southwest coastal Bangladesh. collected monthly paired pond-MAR samples July 2016-June 2017 and enumerated fecal coliforms E. coli using IDEXX quanti-tray technique, by most probable number (MPN) method. used WHO...
