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

objectivesTo examine the relation between static and dynamic blood pressure (BP) measurements and the evolution of kidney function in older people, adjusted for the presence of multimorbidity.

designRetrospective cohort study during a 10-year time interval (2002-2012) in three age strata of patients aged 60 and older.

settingPrimary care registration network with 97 general practitioners working in 55 practices regularly submitting collected patient data.

participantsAll patients with at least one BP measurement in 2002 and at least four serum creatine measurements after 2002 (n=8636). A modified Charlson Comorbidity Index (mCCI) at baseline was registered. Change in systolic and diastolic BP (DBP) and pulse pressure (PP) from 2002 onwards was calculated. The relation between kidney function evolution and baseline BP and change in BP was examined using linear and logistic regression analysis.

main outcome measuresThe slope of the estimated glomerular filtration rate (eGFR, MDRD, Modification of Diet in Renal Disease equation) was calculated by the ordinal least square method. A rapid annual decline of kidney function was defined as ≥ 3 L/min/1.73 m(2)/year.

resultsRapid annual decline of kidney function occurred in 1130 patients (13.1%). High baseline systolic BP (SBP) and PP predicted kidney function decline in participants aged 60-79 years. No correlation between baseline BP and kidney function decline was found in participants aged 80 years and older. An annual decline of ≥ 1 mm Hg in SBP and PP was a strong risk factor for a rapid annual kidney function decline in all age strata, independent of baseline BP and mCCI. A decline in DBP as also a strong independent predictor in participants aged 60-79 years.

conclusionsThe present study identified a decline in BP over time as a strong risk factor for kidney function decline in all age strata, adjusted for mCCI and baseline kidney function and BP.
