Association of Framingham cardiovascular disease risk scores with 10-year risk of cardiovascular mortality: a retrospective cohort study in South India.
Article in Indian heart journal. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundFew cohort studies examine the association of cardiovascular risk scores with cardiovascular mortality in India. This study assessed the association of baseline Framingham Risk Scores (FRS) with 10-year incidence of fatal CVD events in rural Tamil Nadu, India.
methodsUsing a retrospective cohort study design, we analysed the association of baseline FRS categories assessed in 2011-12 through a STEPS risk factor survey, with CVD deaths over 10 years. Causes of death for the survey participants aged 30-64 years at baseline (2011-12), were obtained through established vital event surveillance, while baseline FRS CVD scores were calculated using original and published recalibration equations.
results3418 participants (1480 males, 1938 females), free of CVD at baseline, were followed up for mortality for 10.22 years (median). The CVD mortality rate was 3.01 per 1000 person-years among males and 1.36 in females. Those with baseline original lipid-based FRS ≥20 % had higher CVD mortality risk (Hazard Ratio males: 11.18, 95 % CI: 4.67-26.79; females: 17.51, 95 % CI: 6.07-50.55) compared to those with scores <10 %, with similar results using recalibrated scores. Discrimination statistics (Harrell's C) were 0.755 and 0.751 for original and recalibrated lipid-based scores in males, compared to 0.734 and 0.842 in females.
conclusionsFRS had good predictive validity for cardiovascular mortality in a rural Indian population, confirming its clinical usefulness.
