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

objectivesWe aimed to understand the prevalence of reduced kidney function in China by sociodemographics and geographical region, and to examine health correlates of reduced kidney function.

designCross-sectional study. SETTING AND

participantsParticipants were 6706 adults ≥60 years from the 2015-2016 wave of the China Health and Retirement Longitudinal Study. OUTCOME MEASURES: Reduced kidney function was defined as an estimated glomerular filtration rate of less than 60 mL/min per 1.73 m². The estimated glomerular filtration rate was calculated with the creatinine-cystatin C equation developed by the Chronic Kidney Disease Epidemiology Collaboration in 2012. The associations between reduced kidney function and potential risk factors were analysed using multivariable regression models.

resultsThe prevalence of reduced kidney function was 10.3% (95% CI: 9.3% to 11.2%), corresponding to approximately 20 million older adults. Multivariable analysis showed that older adults with hypertension (β=-3.61, 95% CI: -4.42 to 2.79), cardiac disease (β=-1.90, 95% CI: -2.93 to 0.86), who had a stroke (β=-3.75, 95% CI: -6.35 to 1.15), kidney disease (β=-3.88, 95% CI: -5.62 to 2.13), slow gait speed (β=-2.23, 95% CI: -3.27 to 1.20), and living in the South (β=-4.38, 95% CI: -5.95 to 2.80) and South Central (β=-1.85, 95% CI: -3.15 to 0.56) were more significantly likely to have reduced kidney function.

conclusionsKidney function screening should be performed, especially in patients with hypertension, cardiac disease and who had a stroke. More efforts should be paid to improve the kidney function of older adults living in the South and South Central parts of China.
