Changes in Reported Dietary Supplement Use in Cognitively Normal National Alzheimer's Coordinating Center Participants Aged 55 and Older From 2015 to 2019.
Article in The Journal of nutrition, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundAlthough reported dietary supplement use is common in older adults, evaluations of dietary supplement use over the past 10 y are lacking.
objectiveThis analysis determined changes in reported dietary supplement use in cognitively normal older adults (aged ≥ 55 y) using the National Alzheimer's Coordinating Center data from 2015 to 2019 using a serial cross-sectional study design.
methodsThe first available visit for cognitively normal participants aged ≥ 55 y from 2015 to 2019 with a complete medication form was used, resulting in 9357 participants. Associations between visit year categories and reported use of dietary supplement categories/individual supplements were tested using categorical statistics. To determine whether the probabilities of reported supplement use changed in 2019 compared with those of 2015, z-scores and two-sided P values were used. Weighted analyses were used to confirm analytical findings.
resultsWhen comparing 2015 and 2019, the reported use of any dietary supplement decreased from 77.7% in 2015 to 71.0% in 2019 (P < 0.0001); any vitamin from 72.5% to 65.5% (P < 0.0001); any mineral from 39.2% to 30.4% (P < 0.0001); "other" nonvitamin/nonmineral supplements from 34.4% to 26.9% (P < 0.0001), calcium from 31.2% to 21.7% (P < 0.0001), multivitamins from 48.4% to 38.4% (P < 0.0001), potassium from 5.6% to 3.5% (P = 0.001), vitamin C from 13.0% to 9.2% (P = 0.0002), chondroitin from 6.0% to 4.1% (P = 0.006), glucosamine from 11.1% to 6.5% (P < 0.0001), and all omega fatty acids from 25.2% to 17.0% (P < 0.0001). Reported use increased for vitamin B7/biotin from 3.1% in 2015 to 5.8% in 2019 (P = 0.0003), melatonin from 3.1% to 5.8% (P = 0.0002), and turmeric from 1.2% to 4.7% (P < 0.0001).
conclusionAlthough the reported use of many major dietary supplement categories and individual supplements significantly decreased in older adults from 2015 to 2019, biotin, turmeric, and melatonin significantly increased. Because biotin may interfere with some laboratory tests, this may have important public health implications.
