Description: Estimates adjusted prevalence ratios (PR) and their
        confidence intervals from logistic regression models,
        addressing the well-known limitation of odds ratios (OR) as
        approximations to PR in cross-sectional studies with common
        outcomes. Supports independent observations (glm()),
        clustered/multilevel data (glmer() from 'lme4'), longitudinal
        data via Generalised Estimating Equations (geeglm() from
        'geepack'), and complex survey designs (svyglm() from
        'survey'). Inference is available via the delta method
        (conditional and marginal standardisation) and via bootstrap
        (normal-approximation and percentile intervals). Continuous
        covariates are handled through user-specified or median-based
        reference values; flexible baseline specification allows any
        reference category to be chosen for factor predictors. Based on
        the methodology described in Amorim & Ospina (2021)
