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

backgroundA previous subgroup analysis of a 12-week, double-blind study demonstrated that losartan significantly lowered proteinuria versus placebo and amlodipine and was well tolerated in children (1-17 years old) with proteinuria secondary to Alport syndrome. The present subgroup analysis of the open-label, extension phase of this study assessed the long-term efficacy and tolerability of losartan versus enalapril.

methodsPatients who had completed the double-blind study were re-randomized to losartan or enalapril and followed for proteinuria and renal function for up to 3 years.

resultsTwenty-seven patients with Alport syndrome were randomized to losartan (0.44-2.23 mg/kg/day; n = 15) or enalapril (0.07-0.72 mg/kg/day; n = 12). The least-squares (LS) mean percent change from week 12 in urinary protein to creatinine ratio (UPr/Cr was +1.1 % in the losartan group versus a further 13.9 % reduction in the enalapril group (GMR [95 % CI] = 1.2 [0.7, 2.0]); the LS mean change from week 12 in estimated glomerular filtration rate (eGFR) was -6.4 ml/min/1.73 m(2) in the losartan group versus -9.1 ml/min/1.73 m(2) in the enalapril group. The adverse event incidence was low and comparable in both treatment groups.

conclusionsIn children with proteinuria secondary to Alport syndrome, losartan maintained proteinuria reduction, and enalapril produced a further proteinuria reduction over the 3-year study period. Both agents were generally well tolerated.
