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

objectiveTo estimate the impact and equity of existing and potential UK salt reduction policies on primary prevention of cardiovascular disease (CVD) and gastric cancer (GCa) in England.

designA microsimulation study of a close-to-reality synthetic population. In the first period, 2003-2015, we compared the impact of current policy against a counterfactual 'no intervention' scenario, which assumed salt consumption persisted at 2003 levels. For 2016-2030, we assumed additional legislative policies could achieve a steeper salt decline and we compared this against the counterfactual scenario that the downward trend in salt consumption observed between 2001 and 2011 would continue up to 2030.

settingSynthetic population with similar characteristics to the non-institutionalised population of England.

participantsSynthetic individuals with traits informed by the Health Survey for England. MAIN MEASURE: CVD and GCa cases and deaths prevented or postponed, stratified by fifths of socioeconomic status using the Index of Multiple Deprivation.

resultsSince 2003, current salt policies have prevented or postponed ∼52 000 CVD cases (IQR: 34 000-76 000) and 10 000 CVD deaths (IQR: 3000-17 000). In addition, the current policies have prevented ∼5000 new cases of GCa (IQR: 2000-7000) resulting in about 2000 fewer deaths (IQR: 0-4000). This policy did not reduce socioeconomic inequalities in CVD, and likely increased inequalities in GCa. Additional legislative policies from 2016 could further prevent or postpone ∼19 000 CVD cases (IQR: 8000-30 000) and 3600 deaths by 2030 (IQR: -400-8100) and may reduce inequalities. Similarly for GCa, 1200 cases (IQR: -200-3000) and 700 deaths (IQR: -900-2300) could be prevented or postponed with a neutral impact on inequalities.

conclusionsCurrent salt reduction policies are powerfully effective in reducing the CVD and GCa burdens overall but fail to reduce the inequalities involved. Additional structural policies could achieve further, more equitable health benefits.
