Article in Nutrition & diabetes, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02329990 (Premeal Phosphorus Supplementation for Reducing Energy Intake and Body Weight), which is not on this map. Cited by 19 papers, 1 of them a synthesis that pooled it.

1 · What the graph read from 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.

Abstract

backgroundPhosphorus status is inversely correlated with body weight; however, the effect of phosphorus supplementation on body weight in a controlled design has not been studied.

methodsThis is a double-blind, randomized, placebo-controlled trial of 63 adults aged 18-45 years with a body mass index (BMI) of ⩾25 kg m(-2) and normal kidney function at the American University of Beirut. Participants were randomly assigned to the placebo or phosphorus group where daily placebo or phosphorus supplements were ingested with three main meals (breakfast, lunch and dinner) for a period of 12 weeks. Primary outcomes were changes in anthropometric measures, blood metabolites (including lipid profile, glucose and insulin) and subjective appetite scores. The trial is registered with Clinical Trial.gov, NCT02329990.

resultsBody weight was significantly lower in the phosphorus group when compared with the placebo group (-0.65 kg (95% confidence interval (CI) -1.69 to 0.40) vs 1.13 kg (95% CI 0.19 to 2.06), P=0.01). Similarly, BMI and waist circumference were significantly lower in the phosphorus group when compared with the placebo group (-0.24 kg m(-2) (95% CI -0.59 to 0.12) vs 0.42 kg m(-2) (95% CI 0.05 to 0.78), P=0.01; -3.62 cm (95% CI-4.90 to -2.33) vs 0.38 cm ( 95% CI-0.44 to 1.20), P<0.001; respectively). Several parameters of subjective appetite scores were decreased in the phosphorus-supplemented group.

conclusionsPhosphorus supplementation for 12 weeks significantly decreases body weight, BMI, waist circumference and subjective appetite scores. These findings support a promising role of the mineral phosphorus in the prevention and management of obesity, especially abdominal adiposity. The exact mechanisms of action and longer-term effects still need to be elucidated.
