Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomization numbers will be allocated to patients using a computer-generated randomization schedule. Each participant will be assigned a unique identifier corresponding to their treatment group. This process will be conducted by qualified personnel not involved in participant assessments to ensure unbiased and unpredictable treatment assignments. The randomization code will remain confidential until the completion of the study.

The study products, whether investigational or control, will be uniformly packaged to maintain identical appearance, texture, and any other relevant characteristics. Packaging will be devoid of any identifiable markings that could reveal the nature of the contained product.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization numbers will be allocated to patients using a computer-generated randomization schedule. Each participant will be assigned a unique identifier corresponding to their treatment group. This process will be conducted by qualified personnel not involved in participant assessments to ensure unbiased and unpredictable treatment assignments. The randomization code will remain confidential until the completion of the study.

Statistical methods / analysis
The descriptive statistics for continuous variables will be presented with the number (n) of non-missing observations, mean, SD, median, and minimum and maximum (range). For categorical data, the descriptive statistics will be presented with the number of exposed patients and number (n) with a percentage of observations in the various categories of the endpoint, where the percentage will be based on the exposed patients. Descriptive analyses will also include graphical presentations of data wherever appropriate.
Given the non-inferiority nature of this trial, the primary analysis will focus on demonstrating the non-inferiority of Iron (III) Hydroxide Polymaltose 100mg Hard Gelatin Capsules compared to Maltofer® 370 mg Tablets (100mg iron as iron polymaltose). A one-sided statistical test will be employed to assess non-inferiority, utilizing a pre-specified margin of non-inferiority. This margin will be justified based on clinical relevance and prior literature.
Individual patient data listings will be provided, encompassing pregnant and non-pregnant women, as well as men diagnosed with iron deficiency. All analyses will be conducted using two-sided tests for secondary endpoints and where applicable. Subgroup analyses, particularly considering mild to moderate subgroups, will be performed for both primary and secondary endpoints.
A detailed SAP will be finalized, providing comprehensive methods for the analyses outlined above, before the database is locked and prior to the initiation of the trial's analysis. Any deviations from the analyses described above will be explicitly documented in the SAP. The statistical analysis will be performed using SAS software version 9.4 or higher (SAS Institute Inc., Cary, NC, USA).
