Association between Adiposity and Iron Status in Women of Reproductive Age: Data from the UK National Diet and Nutrition Survey (NDNS) 2008-2019.
Article in The Journal of nutrition, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 papers.
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
backgroundOverweight/obesity and iron deficiency (ID) are highly prevalent in women of reproductive age (WRA), impacting on women's health. Obesity is a risk factor for nutritional deficiencies but its association with ID is unclear.
objectivesTo determine the association between adiposity and markers of iron status and ID prevalence in WRA.
methodsThis cross-sectional study analyzed the National Diet and Nutrition Survey (2008-2019) data, focusing on women aged 18-49 y with body mass index (BMI) ≥18.5 kg/m
resultsAmong 1098 WRA, 496 normal weight and 602 overweight/obesity, prevalence rates were: anemia 9.2% and IDA 6.8%. Anemia was more prevalent in those with higher WHtR and WHR (11.9% compared with 5.9% and 16.7% compared with 6.5%, both P < 0.001). WRA with increased WC, WHtR, and WHR had higher IDA prevalence than those with lower adiposity (8.5% compared with 4.3%, P = 0.005; 9.4% compared with 3.3%, P < 0.001; 12.1% compared with 4.9%, P < 0.001). ID prevalence was 49.7% (ferritin cutoff 30 μg/L) and 19.6% (ferritin cutoff 15 μg/L), showing similar rates across adiposity groups. ID prevalence defined by soluble transferrin receptor (sTfR) was higher in women with increased WHR (P = 0.001). Higher WHR predicted ID categorized by sTfR (adjusted odds ratio [aOR]: 2.104, P = 0.004), and WHtR and WHR predicted anemia and IDA (anemia: WHtR aOR: 2.006, P = 0.036; WHR aOR: 4.489, P < 0.001 and IDA: WHtR aOR: 2.942, P = 0.012; WHR aOR: 4.142, P < 0.001).
conclusionsAt least 1 in 5 WRA in the UK are iron deficient, highlighting the need to revise current policies. Greater central adiposity was strongly associated with impaired iron status and the development of anemia, IDA, and ID.
