Urinary sodium excretion and dietary sources of sodium intake in community-dwelling Chinese adults aged 50 years and over.
Trial report in Public health nutrition, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveThis study examined Na intake and identified the major food sources of Na in healthy Chinese adults aged ≥50 years in Hong Kong.
designParticipants who completed a baseline assessment of a randomised controlled trial assessing the effectiveness of exercise and nutrition supplementation on improving physical and cognitive functions were included. A single 24-h urine sample and a 3-d diet record were used to measure urinary Na excretion and dietary intake, respectively. The compliances to the WHO (<5 g/d) and China Nutrition Society (<6 g/d) recommendations for salt intake were assessed based on the urinary Na excretion. The relative contribution of sixteen food groups to the dietary Na intake was expressed as percentages. Associations between food groups and urinary Na excretion were analysed using multiple linear regression.
settingCommunity facilities.
participantsTotally, 114 healthy Chinese adults (mean age 60·6 years, 55 % women).
resultsThe mean urinary Na excretion over 24-h was 2876·6 ± 1249·4 mg/d (7·3 ± 3·2 g salt/d). Overall, 22·8 % of participants met the WHO recommendation and 34·2 % met the Chinese Nutrition Society recommendation for salt intake. The major food sources of dietary Na intake were condiments (42·4 %), cereals and their products (16·8 %) and soups (13·5 %). Higher intakes of seafood and nuts were associated with lower urinary Na excretion.
conclusionsPublic health strategies should target healthy Chinese adults in Hong Kong to modify the current patterns of Na intake. Targeting condiments, cereals and their products and soups will be an important strategy to reduce their Na intake.
