A Cross-Sectional Study of Postpartum Changes in Bone Status in Indian Mothers.
Article in Journal of obstetrics and gynaecology of India, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBone turnover is high during lactation. However, studies on bone status of Indian urban mothers are scarce. Hence, the objective was to conduct a cross-sectional study on the lactation-related changes in bone health status of Indian mothers postpartum using Dual X-ray Absorptiometry (DXA) at 3 time points: within a week of delivery, at 1- and 3-years postpartum. We also explored the association of dietary calcium intake, physical activity, serum vitamin D status, and dietary traditional food supplements (Dietary Food supplements) with bone health.
methodsA cross-sectional study was conducted; 300 full-term, healthy primiparous women (28.6 ± 3.4 year) were randomly selected and categorized into 3 groups: 128 mothers within 7 days of delivery (Group A), 88 with 1-year-old children (B), and 84 with 3-year-old children (C). Anthropometry, lactation history, physical activity, diet, biochemical tests (vitamin D, parathyroid hormone), body composition, areal bone mineral density (a-BMD) at total body (TB), AP spine (APS), and dual neck femur (DF) were assessed by DXA (GE-Lunar DPX).
resultsSignificantly higher APS-BMD (mean ± SD) was observed in Group C (1.107 ± 0.098 g/cm(2)) than that in A (1.045 ± 0.131 g/cm(2)) (p < 0.05). When adjusted for breastfeeding practices, mean (±standard error) APS-BMD was lowest in women in Group A (1.024 ± 0.013 g/cm(2)), but was higher at 1-year (1.079 ± 0.02 g/cm(2)) and at 3-years postpartum (1.111 ± 0.019 g/cm(2)), though differences were significant only between groups A and C (p < 0.05). Most mothers from all 3 groups consumed inadequate amount of nutrients except dietary fat and showed low physical activity. Multiple regression analysis indicated that dietary calcium, moderate physical activity, serum vitamin D, and consumption of dietary food supplements were not significant predictors of APS-BMD (p > 0.1).
conclusionPrevalence of nutrient and vitamin D deficiencies, low physical activity, and poor sunlight exposure were major concerns in Indian lactating mothers; improvement in bone mass at APS was observed at 3-years which was most likely due to physiologic changes.
