Changes in version 0.3.2 (2026-06-03)                  

New Functions and Functionality

  - Added g_lineplot() for creating line plots with optional summary
    statistics table. Includes helper functions calc_stats(),
    g_lineplot_table(), and preprocess_lineplot_data().

  - Added ard_tabulate_abnormal_by_baseline() for creating an Analysis
    Results Data (ARD) object counting participants with abnormal
    assessments, stratified by their baseline status.

  - Added tbl_mmrm() and get_mmrm_results() functions to create
    regression tables for Mixed Models for Repeated Measures (MMRM).
    (#163)

  - Added gg_mmrm_lineplot() to create line plots of MMRM results.
    (#181)

  - Added gg_pkc_lineplot() to create line plots for PK data. (#185)

  - Added annotate_gg_pkc() to add optional summary statistics table to
    gg_pkc_lineplot(). (#189)

  - Refactored the underlying data.frame alignment and rendering
    methodology used for plot annotations. Functions for table
    annotation now use a completely rebuilt engine that ensures X-axis
    synchronization for stacked tables (annotate_riskdf()) and flexible,
    reliable placement for floating tables (annotate_surv_med(),
    annotate_coxph()). (#189)

  - Refactored functions for lineplot plotting - added gg_lineplot() and
    annotate_gg() to create lineplots and annotate summary statistics
    table. (#184)

  - Added functions reverse_ci(), reverse_rate_difference() to reverse
    confidence intervals and rate differences in tables from
    add_row_difference(). (#204)

  - g_lineplot(), g_lineplot_table(), and preprocess_lineplot_data()
    were deprecated. (#184)

  - Added tbl_coxph() to render pairwise Cox proportional hazards
    results as a gtsummary table. (#159)

  - Added tbl_hierarchical_incidence_rate() which computes the incidence
    rate of adverse events (#211)

  - Added adjust_stat_columns_wrap() which keep the presentation of
    statistics in one row (#219)

  - get_cox_pairwise_df() now allows for different methods to compute
    p-value (#191) and to handle ties (#193).

  - tbl_coxph() now accepts a data.frame created by
    get_cox_pairwise_df() as input. (#207)

  - Added add_grade_column() to inject a grade-label column into
    tbl_hierarchical_rate_by_grade() output. Decoupled from the table
    builder to prevent Cartesian join explosion in tbl_merge(). (#226)

  - get_cox_pairwise_df() now fully supports strata() terms in survival
    formulas (#256).

  - The "likelihood-ratio" test now intelligently switches between
    survival::survreg() (for unstratified models) and survival::coxph()
    (for stratified models) (#256).

  - Stripped package namespace prefixes (e.g., survival::) from survival
    formulas to prevent evaluation errors (#256).

  - Added ... support in get_cox_pairwise_df() for conf.int (e.g., to
    adjust CI level) and robust = TRUE (for robust standard errors).

Other Updates

  - tbl_hierarchical_rate_and_count() now emits zero-rows for unobserved
    factor levels in the first hierarchical variable. (#233)

  - df2gg_aligned() and df2gg_floating() now preserve original ggplot
    objects in attr(result, "plotlist") for downstream data extraction
    after combining with cowplot. (#208)

  - Remove warning when data has more levels than needed for
    grade_groups on tbl_hierarchical_rate_by_grade.

  - Changed the default conf.type from "log" to "plain" (linear) in
    tbl_survfit_times() and tbl_survfit_quantiles() to align with GDSR
    guidelines. (#173)

  - Removed bold from headers when using tbl_strata() (#133).

  - Unified border width in theme_gtsummary_roche() to 0.5 for header.
    (#154)

  - Added example on how to stratify tbl_baseline_chg() by PARAM and
    split into a list.

  - Adjusted tbl_mmrm() to allow base_df = NULL.

  - Fixed two bugs related to summary statistics calculation in
    ard_tabulate_abnormal_by_baseline(). (#198)

  - Fixed a bug in gg_pkc_lineplot() causing misplaced error bars on a
    log scale. (#199)

  - Adjusted gg_pkc_lineplot() to use tbl_roche_summary() for automatic
    decimals formatting.

  - Adjusted tbl_hierarchical_incidence_rate() to handle first event as
    well as all events (#217)

  - Adjusted tbl_baseline_chg() to allow for custiomization of display
    statistics (#222)

  - Changed baseline statistic argument in tbl_baseline_chg() (#224)

  - Adjusted modify_zero_recode() to account for strings comprising
    regular and non-breaking spaces (#230)

  - tbl_roche_subgroups() now shows n, Events, and Median per arm when
    time_to_event is specified. The total column shows Total Events
    instead of Total n. (#235)

  - Skip tests if suggested packages are missing (Failing test due to
    missing suggested package #252, @llrs-roche)

  - The default "log-rank" test now uses survival::survdiff() instead of
    coin, aligning output more closely with SAS and rtables

  - Added tbl_subgroups and g_forest to make subgroup analysis and
