Causes of widening life expectancy inequalities in Québec, Canada, 1989-2004.

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
objectivesInequalities in life expectancy between the most and least materially deprived areas in the province of Quebec, Canada are increasing, but the reasons for this trend are unclear. An analysis of which causes of death, in which age groups, are implicated in this trend is necessary to understand it and provide clear targets for intervention.
methodsWe analyzed Quebec mortality data for three 4-year periods from 1989-2004. Differences in life expectancy at birth between the most- and least-deprived areas in each period and over time were decomposed by age and cause of death for men and women using the Arriaga method.
resultsLife expectancy increased for all areas, but the increase was smaller in deprived areas. Cancer, heart disease and unintentional injuries accounted for the largest shares of inequality in each period. Among women, the widening life expectancy gap was largely due to increased lung cancer mortality. Among men, mortality from HIV was an important cause of widening inequality. Increasing inequality in both sexes was offset by a decrease in mortality from unintentional injuries in deprived areas (narrowing the gap between the most- and least-deprived areas). The largest share of inequality among women was due to deaths in the 65-and-over age group. Among men, the largest share shifted over time from middle-age to the 65-and-over age group.
conclusionThe widening life expectancy gap between advantaged and disadvantaged areas in Quebec is driven by relatively few causes of death with well-known risk factors and strategies for prevention.
