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

backgroundChronic kidney disease (CKD) is common in the elderly, but the cause is often not identifiable. Some posit that age-related reductions in glomerular filtration rate (GFR) and increases in albuminuria are normal, whereas others suggest that they are a consequence of vascular disease. STUDY

designCross-sectional analysis of a substudy of a prospective cohort. SETTING &

participantsAGES (Age, Gene/Environment Susceptibility)-Reykjavik Study. PREDICTOR: Exposure to higher blood pressure in midlife. OUTCOMES & MEASUREMENTS: Measured GFR using plasma clearance of iohexol and urine albumin-creatinine ratio.

resultsGFR was measured in 805 participants with mean age in midlife and late life of 51.0±5.8 and 80.8±4.0 (SD) years, respectively. Mean measured GFR was 62.4±16.5 mL/min/1.73 m(2) and median albuminuria was 8.0 (IQR, 5.4-16.5) mg/g. Higher midlife systolic and diastolic blood pressures were associated with lower later-life GFRs. Associations persisted after adjustment. Higher midlife systolic and diastolic blood pressures were also associated with higher albumin-creatinine ratios, and associations remained significant even after adjustment. LIMITATIONS: This is a study of survivors, and people who agreed to participate in this study were healthier than those who refused. Blood pressure may encompass effects of the other risk factors. Results may not be generalizable to populations of other races. We were not able to adjust for measured GFR or albuminuria at the midlife visit.

conclusionsFactors other than advanced age may account for the high prevalence of CKD in the elderly. Midlife factors are potential contributing factors to late-life kidney disease. Further studies are needed to identify and treat midlife modifiable factors to prevent the development of CKD.
