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

backgroundLow uric acid (UA) levels are desirable in kidney disease. Enalapril is the most used reno-protective drug; losartan has a similar antihypertensive and antiproteinuric effect, but also induces hyperuricosuria due to tubular urate transporter 1 inhibition. As this effect has not been demonstrated in paediatrics, we assessed if losartan reduces serum UA in children, owing to an increase in its urinary excretion, compared to enalapril.

methodsSingle-centre, open-label, crossover randomized trial. Patients aged 3-12 years with proteinuric kidney disease and estimated glomerular filtration rate ≥ 30 ml/min/1.73 m

resultsForty patients were included (36 CKD stage 1, 4 stage 2), median age 8.58 years; median serum UA 4 mg/dL (IQR, 3.5-5.1). Losartan significantly increased median UA urinary fractional excretion from 7% (IQR 6-8.27) to 8.9% (IQR 6.3-11) (p < 0.001) and significantly reduced its median serum level from 4.2 mg/dL (IQR 3.4-4.9) to 3.6 mg/dL (IQR 2.9-4.5) (p < 0.001). Median urinary excretion [pre 6.65% (IQR 5-8.41) vs. post 7% (IQR 5.5-8.3), p = 0.61)] and median serum values [pre 4.2 mg/dL (IQR 3.6-5.1) vs. post 4.1 mg/dL (IQR 3.4-5), p = 0.42)] were comparable with enalapril. The decrease in serum UA levels post-losartan correlated with the increase in its urinary excretion (r = -0.33; p = 0.036).

conclusionsLosartan significantly increased UA urinary excretion along with the consequent reduction in its serum levels.
