1. IntroductionWith rapid population growth, water consumption by industry, agriculture, and households continues to increase [1], leading to water pollution as a global issue [2]. Synthetic dyes are among the most harmful chemical pollutants in water [3], and water contaminated by them can cause serious health problems [4,5], hence the need for wastewater treatment. Methods of treating water pollutants can be divided into physical, chemical, and biological methods [6].

Statistical analysesWe conducted 2-stage pooled analyses for risk factors of interest that were measured in at least 3 studies. In a few cases, we excluded studies if the risk factor had an extremely high number of missing values. These analyses involved first estimating study-specific regression coefficients using modified Poisson regression with robust variance estimates and pooling all regression coefficients in a meta-analysis.
