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

backgroundGovernments are incentivized to develop and implement health action programs focused on equity to ensure progress with effective strategies or interventions.

objectiveIdentify and synthesize strategies or interventions that facilitate the reduction of health inequalities.

methodsA systematic search strategy was carried out up until August 2019 in MEDLINE (Ovid), Embase (Elsevier), Cochrane Database of Systematic Reviews, LILACS, Scopus, Scielo and Epistemonikos. In addition, a snowball strategy was used. Literature reviews (LRs) of experimental and quasi-experimental studies were included. The identified interventions and outcomes were categorized based on the recommendation by the Cochrane group in "Effective Practice and Organization of Care". The quality of the included LRs was evaluated using the AMSTAR 2 tool.

resultsFour thousand ninety-five articles were identified, of which 97 were included in the synthesis of evidence. Most of the studies included focused on the general population, vulnerable populations and minority populations. The subjects of general health and healthy lifestyles were the most commonly addressed. According to the classification of the type of intervention, the domain covered most was the delivery arrangements, followed by the domain of implementation strategies. The most frequent group of outcomes was the reported outcome in (clinical) patients, followed by social outcomes.

conclusionThe strategies that facilitate the reduction of health inequalities must be intersectoral and multidisciplinary in nature, including all sectors of the health system. It is essential to continue generating interventions focused on strengthening health systems in order to achieve adequate universal health coverage, with a process of comprehensive and quality care.
