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

BACKGROUND/

objectivesPrevious studies have shown an upward trend in the prevalence of hypertension, but data on trend of incidence of hypertension are lacking. We seek to investigate the trends in incidence of hypertension and control of incident hypertension among Chinese adults during 1991-1997 and 2004-2009.

methodsWithin the China Health and Nutrition Survey (1991-2009), we identified five cohorts of adults (age ≥ 18 years) who were free of hypertension at baseline of each cohort: cohorts 1991-1997 (n=4107), 1993-2000 (n=4068), 1997-2004 (n=4141), 2000-2006 (n=4695), and 2004-2009 (n=4523). Data on demographics, smoking, alcohol intake, physical activity, body mass index (BMI), and blood pressure were collected through interviews and clinical examination. Hypertension was defined as blood pressure ≥ 140/90 mmHg or currently using antihypertensive drugs. Multiple generalized estimation equations and Coxregression models were used to test the trends in blood pressure, incidence of hypertension, use of antihypertensive drugs, and control status of incident hypertension.

resultsAfter controlling for potential confounders, incidence of hypertension (per 100 person-years) significantly increased from 2.9 in 1991-1997 to 5.3 in 2004-2009 (ptrend=0.024); the linear trend was statistically or marginally significant in the age group of 18-39 years, in women, in rural residents, and in adults with normal BMI. The overall rates of antihypertensive treatment and control of incident hypertension increased significantly from 5.7% and 1.7% in 1991-1997 to 19.9% and 7.6% in 2004-2009, respectively (ptrend<0.001).

conclusionsThe incidence of hypertension has increased in Chinese adults since early 1990s. The treatment and control status of incident hypertension, while improved, remain very poor.
