Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
1.Non-iron deficiency anemia or other hematologic disorders: thalassemia, sickle cell anemia, anemia of chronic disease, and other hematologic conditions will be excluded based on complete blood count findings (including concentration) in combination with questionnaire assessment. Renal insufficiency ( \<45 mL/min/1.73 m²)
2: hepatic insufficiency ( or AST >3 times the )
3: uncontrolled heart disease ( [NYHA] functional class III-IV) Acute or chronic infections, including infection, active tuberculosis, and uncontrolled Multiple pregnancy
4: current pregnancy complicated by major fetal malformations or chromosomal abnormalities
5: history or current diagnosis of preeclampsia, placental abruption, or placenta previa History of to intravenous iron therapy or iron overload disorders
6: receipt of blood transfusion or intravenous iron therapy within 1 month before enrollment Psychiatric disorders or cognitive impairment that would interfere with study participation or compliance with study procedures
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Townships assigned to this group implement anemia screening and indicated iron treatment before conception.
Other: Preconception Anemia Screening and Treatment Strategy
Townships assigned to this group implement the same anemia screening and indicated iron treatment during early pregnancy.
Other: Early-Pregnancy Anemia Screening and Treatment Strategy
Women planning pregnancy within 6 months undergo hemoglobin, hemoglobin electrophoresis, and serum ferritin assessments before conception. Those with hemoglobin levels below 120 g/L and/or serum ferritin levels below 30 μg/L receive oral ferrous succinate (0.2 g twice daily) plus vitamin C, with scheduled hematologic monitoring.
Women with a singleton pregnancy at 12 weeks' gestation who have hemoglobin levels below 110 g/L and/or serum ferritin levels below 30 μg/L will receive oral ferrous succinate (0.2 g twice daily) plus vitamin C, with scheduled hematologic monitoring
Proportion of participants with iron deficiency anemia during late pregnancy
Iron deficiency anemia is defined as a hemoglobin concentration of less than 110 g/L and a serum ferritin concentration of less than 20 μg/L, measured in the same blood sample. Participants meeting both criteria at least once during any scheduled assessment from 28 weeks' gestation through delivery will be classified as having the primary outcome.
Time frame: From 28 weeks' gestation to delivery
