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

aimTo explore whether long-term adherence to preventive statin therapy depends on socioeconomic position (SEP).

methodsA cohort of individuals without established cardiovascular disease (CVD) or diabetes initiating preventive statin therapy during 2002-2005 was followed in the individual-level Danish registries for 4 years or until censoring events (death, emigration, CVD or diabetes). Only individuals aged 40-84 years for whom information was available on the SEP indicators, education and income were included (N = 76,038). Two different aspects of poor adherence were applied as outcome measures: (1) Proportion of days covered (PDC) with medication below 80 %, assuming a daily dose of one tablet (continuity); (2) Discontinuation defined as a gap between two consecutive prescriptions exceeding 365 days (persistence). Stratum-specific logistic regression analyses were applied to estimate the odds ratio (OR) for PDC <80 % across SEP, adjusting for age and hypertension. Hazard ratio (HR) for discontinuation was estimated by Cox regression analyses.

resultsAdjusting mutually for income and education, the OR for PDC <80 % decreased with increasing income. Comparing the highest income quintile with the lowest, the OR were 0.64 (95 % Confidence Interval 0.64-0.65) and 0.73 (0.73-0.74) in men aged 40-64 and 65-84 years, respectively; in women, the figures were 0.79 (0.79-0.79) and 0.95 (0.94-0.95), respectively. While observed increases in adherence with longer education in unadjusted analyses were attenuated after adjustment for income among men, the potential inverse relationship between length of education and adherence was enhanced among women. Applying discontinuation as outcome, analogous differences were demonstrated.

conclusionAdherence to preventive statin therapy in Denmark decreases with decreasing income-especially in men aged 40-64 years.
