A Community-Level Sodium Reduction Intervention, Boston, 2013-2015.
Article in American journal of public health, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
objectivesTo evaluate a community-level sodium-reduction intervention in Boston, Massachusetts. Reducing sodium in the food offerings of community settings may help reduce hypertension disparities.
methodsWe examined changes in the proportion of prepackaged foods with greater than 200 milligrams of sodium in 7 hospitals, 8 YMCAs, 4 community health centers, and 2 organizations serving homeless populations. Research assistants documented prepackaged items in cafeterias, kiosks, and vending machines before and after the intervention (2013-2015). We assessed intervention change via linear mixed models accounting for repeated observations.
resultsThere were 161 access points at baseline (4347 facings) and 171 (4996 facings) at follow-up. The percentage of prepackaged products with greater than 200 milligrams of sodium decreased from 29.0% at baseline to 21.5% at follow-up (P = .003). Changes were driven by improvements in hospital cafeterias and kiosks (P = .003). The percentage of products with greater than 200 milligrams of sodium in YMCA vending decreased 58% (from 27.2% to 11.5%; P = .017); other organizations had nonsignificant declines.
conclusionsWe found modest reductions in the percentage of higher-sodium prepackaged products across community institutions. Community-level interventions may increase availability of lower-sodium products in the food supply.
