Effect of any iron-folic acid (IFA) supplements, number of supplements used, timing of start of supplements and timing of start with number of supplements used on early neonatal mortality determined by multivariate analysis in Nepal and Pakistan.

927 missing values were excluded from the pooled NDHS analysis and 696 missing values were excluded from the pooled PDHS analysis. Further, we excluded 416 and 1489 cases with implausible values of IFA supplements consumed from the analysis of number of IFA supplements used in NDHS and PDHS respectively.
*Both models were adjusted for region/province and area of residence, maternal marital status, maternal level of attained education, maternal occupation, paternal level of attained education, paternal occupation, pooled household wealth index, maternal age at childbirth, child's sex, a combined variable birth rank and birth interval, maternal desire for the pregnancy, maternal perceived birth size, timing of initiation of breastfeeding, place of delivery, a combined variable for mode of delivery with delivery assistance, duration of recall period, year of birth of the child and the average cluster coverage of Bacillus Calmette-Guerin (BCG) vaccine.
aHR: Adjusted Hazard Ratio.
CI: Confidence Interval.
NDHS: Nepal Demographic and Health Survey.
PDHS: Pakistan Demographic and Health Survey.

合并后的尼泊尔人口与健康调查（Nepal Demographic and Health Survey, NDHS）分析中共剔除927条缺失值，合并后的巴基斯坦人口与健康调查（Pakistan Demographic and Health Survey, PDHS）分析中共剔除696条缺失值。此外，针对NDHS与PDHS中叶酸铁补充剂（iron-folic acid, IFA）服用剂量的分析，我们分别剔除了416例与1489例服用IFA剂量不合理的研究样本。
*两项模型均校正了以下混杂因素：地区/省份与居住区域、产妇婚姻状况、产妇受教育程度、产妇职业、父亲受教育程度、父亲职业、合并家庭财富指数、产妇分娩时年龄、新生儿性别、出生胎次与出生间隔组合变量、产妇妊娠意愿、产妇感知的新生儿出生大小、母乳喂养启动时机、分娩地点、分娩方式与助产情况组合变量、回忆周期时长、新生儿出生年份以及卡介苗（Bacillus Calmette-Guerin, BCG）疫苗的整群平均接种覆盖率。
aHR：校正后风险比（Adjusted Hazard Ratio）
CI：置信区间（Confidence Interval）

本研究借助多因素分析，探究了叶酸铁补充剂服用情况、补充剂服用剂量、补充剂启动时机，以及启动时机联合服用剂量对尼泊尔与巴基斯坦两国早期新生儿死亡率的影响。
