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.

2 · The registry

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

High blood pressure (BP) is extremely common in persons with obesity. However, not all obese individuals have high BP, nor does weight loss lower BP in all persons. In this study, the authors investigated whether the salt-sensitive (SS) or salt-resistant (SR) phenotype determines the degree of BP lowering induced by weight loss in a group of middle-aged individuals of whom 80% are of Hispanic descent. Overweight/obese participants classified as SS or SR (N=45; body mass index, 27-35 kg/m(2)) entered a 1-year program of dietary restriction, aerobic exercise, and metformin therapy. Comparable reductions in obesity (8%-10%), triglycerides (25%), and fasting insulin concentrations (40%) were observed in SR and SS individuals. In SS patients, the intervention lowered systolic BP/diastolic BP by 8.8/6.1 mm Hg, decreased albuminuria by 63%, and decreased the patient's salt sensitivity. Neither BP nor albuminuria was modified in SR persons by the intervention. In obese SS individuals, salt restriction induced comparable BP lowering as weight reduction. In summary, BP lowering induced by the lifestyle/metformin intervention appears to be determined by the SR/SS phenotype. Weight loss and correction of metabolic abnormalities lowers BP in obese SS persons but not in obese SR persons. Correcting adiposity in SS patients lowers BP by making the BP insensitive to dietary salt. The SR phenotype protects from obesity-induced increases in BP.
