Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
We will conduct a non-inferiority, double blind, individually randomized controlled trial in non-pregnant women of reproductive age with iron deficiency anaemia (haemoglobin <120 g/L & serum ferritin <30 µg/L) to assess the haemoglobin and iron status in response to i) 200mg oral bovine lactoferrin, ii) 400mg of oral bovine lactoferrin iii) standard oral iron supplements (60mg elemental iron). The intervention (each capsule once daily) will be continued for 3 months. Study personnel (field implementer and study physicians) will have monthly contacts with the enrolled women for monitoring compliance to intervention.

Statistical methods / analysis
The estimated sample size is for a non-inferiority two-sample comparison of means for each dose of lactoferrin. The null hypothesis is that the degree of inferiority of the haemoglobin response after one month of oral bovine lactoferrin (L) to standard oral iron supplements (I), I-L, is greater than the margin M thus ruling out a degree of inferiority greater than the margin M.
Ho: I-L = M (L is more inferior to I than M)
Ha: I-L < M (L is less inferior to I than M)
Assumptions:
• Based on evidence from prior studies the response of iron compared to placebo is 10.0 g/L, and M, the largest clinically acceptable difference, is 2.5 g/L.
• Expected standard deviation = 0.80 (in each group)
• Power = 0.80
• Alpha = 0.025 (one-sided)
The estimated required sample size per group is 161, giving a total sample size of 483 for the 3 treatment groups.
Since 15% of subjects are expected to be lost to follow-up, the total sample size is adjusted to 556.
Calculation based on 'SSI': module to estimate sample size for RCTs in Stata version 14.

Analysis Plan
Participants who will receive at least one dose of supplement and at least one post-baseline efficacy assessment during the double-blind part will be included in the analysis. All analysis will be conducted at individual level. We will analyze patients categorized by the treatment group to which they will be allocated on an intention-to-treat (ITT) basis. The last day of follow up will be considered as outcome status for study participants who may be lost to follow-up without having the outcome of interest. To obtain the overall across-dose-range treatment (Lactoferrin and IFA supplements) effects, the average differences between log-dose slopes for percent changes from baseline in iron status and inflammatory biomarkers will be obtained in separate analyses (ANOVA) for all arms of part one. For safety analyses, descriptive statistics will be included for all parameters and an analysis of variance model (ANOVA) will be used for between-group (treatment arms) and within group (anaemic and mild anaemic) comparisons. For subgroup analyses, we will use Cox proportional hazard models (for mortality outcome), and other generalized linear mixed models (for preterm and low birth-weight outcomes) that will incorporate each of the major covariates. Statistical significance will be considered at p<0·05. Models will be able to evaluate the impact of the interventions by testing for interactions over time in all intervention groups. Analysis will be conducted to identify covariates that influence the response to interventions (based on household wealth, maternal education, or income).

Summary
Brief summary
Hypotheses:
• Oral bovine lactoferrin is at least as effective in correcting iron deficiency anaemia among non-pregnant women of reproductive age compared to standard iron supplements.

Objectives:
1. To determine the optimal dose of oral bovine lactoferrin for correction and prevention of iron deficiency anaemia in women of reproductive age.
2. To determine whether bovine lactoferrin is at least as effective as oral iron in treating iron deficiency anaemia among non-pregnant women of reproductive age.
3. To compare the side-effects of oral iron supplements and bovine lactoferrin
4. To compare the adherence of oral iron supplements and bovine lactoferrin

Methods:
We will conduct a non-inferiority randomized controlled trial (RCT), to compare different doses of oral bovine lactoferrin with standard oral iron supplements in non-pregnant anaemic women of reproductive age to determine the appropriate dose of bovine lactoferrin, and demonstrate it is safe and as effective as standard oral iron supplements in treating iron deficiency anaemia.

Outcome measures/variables:
The primary outcome will be the change in haemoglobin concentration from baseline to the end of the twelfth week of treatment.
