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

backgroundTo guide resource allocation, policy makers need evidence of the cost-effectiveness of interventions. We summarized such evidence on selected interventions to reduce sodium intake that would be intended as population-wide approaches to control hypertension.

methodsWe conducted a comprehensive literature review of journal articles published in English from January 2000 to May 2010 by searching the databases of PubMed, EMBASE, MEDLINE, and EconLit. We selected original research articles for abstracting the evidence on cost-effectiveness of interventions, cost savings and the costs of intervention implementation.

resultsFrom the 53 references obtained from the literature search, we identified 11 original research articles that provided relevant information on the medical cost savings, implementation costs, or cost-effectiveness of interventions to reduce sodium intake. The interventions were low in cost, e. g., one study showed that the cost ranged from US$ 0.03 to 0.32 per person per year for awareness campaign through mass media outlets and government regulations on food products in low and middle-income countries. Population-wide interventions for salt reduction are very cost-effective such as only ARS$ 151 per disability-adjusted life-year (DALY) saved in Argentina, whereas statin therapy to lower high cholesterol was $ 70,994 per DALY saved. Another study showed that sodium reduction could save US$ 18 billion in annual US healthcare costs by reducing sodium intake to 2300 mg/day.

conclusionThe literature provided economic evidence that was in favor of population-wide interventions designed to reduce sodium intake. Reducing the intake of sodium through such initiatives might be one of the best buys in public health. However, the small body of literature and hypothetical scenarios in most studies might limit policy implications of the findings.
