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

backgroundIncreasing differences in cardiovascular disease (CVD) mortality across levels of education have been reported in Norway. The aim of the study was to investigate educational inequalities in acute myocardial infarction (AMI) incidence and whether such inequalities have changed during the past decade using a nationwide longitudinal study design.

methodsData on 141 332 incident (first) AMIs in Norway during 2001-2009 were obtained through the Cardiovascular Disease in Norway (CVDNOR) project. Educational inequalities in AMI incidence were assessed in terms of age-standardised incidence rates stratified on educational level, incidence rate ratios (IRR), relative index of inequality (RII) and slope index of inequality (SII). All calculations were conducted in four gender and age strata: Men and women aged 35-69 and 70-94 years.

resultsAMI Incidence rates decreased during 2001-2009 for all educational levels except in women aged 35-69 among whom only those with basic education had a significant decrease. In all gender and age groups; those with the highest educational level had the lowest rates. The strongest relative difference was found among women aged 35-69, with IRR (95% CI) for basic versus tertiary education 3.04 (2.85-3.24)) and RII (95% CI) equal to 4.36 (4.03-4.71). The relative differences did not change during 2001-2009 in any of the four gender and age groups, but absolute inequalities measured as SII decreased among the oldest men and women.

conclusionsThere are substantial educational inequalities in AMI incidence in Norway, especially for women aged 35-69. Relative inequalities did not change from 2001 to 2009.
