Autosomal dominant polycystic kidney disease: new role for ultrasound.

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.
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 evaluate the accuracy of US in calculating renal volumes and renal resistive index (RRI) that was obtained using a new method in patients with autosomal dominant polycystic kidney disease (ADPKD).
methodsIn this prospective study, US and MRI were performed in 57 patients with ADPKD (31 female and 26 male; age range, 19-79 years) between August 2017 and May 2018. The volumes determined using US and MRI were compared. The ellipsoid formula was re-evaluated using different multipliers. RRI was obtained 1.5-2 cm distal to the outlet of main renal arteries. The relationship between mean RRI, renal function tests, and kidney volumes and difference between mean RRI of ADPKD patients with and without renal failure were investigated using a two-sided independent samples t test and Pearson correlation test. Interobserver agreements for volume assessments and RRI measurements were determined.
resultsBy changing the ellipsoid formula, a very good agreement was found (ICC 0.970 for the right kidney and ICC 0.973 for the left kidney). The mean RRI in the right renal artery was 0.61 ± 0.07 and in the left renal artery 0.63 ± 0.06. The mean RRI of ADPKD patients with renal failure was significantly higher than that of patients without renal failure (p = 0.005). There was a significant correlation between mean RRI and renal function tests.
conclusionThe accuracy of the US in calculating renal volumes increases by adapting the ellipsoid formula. RRI may be used for the management of ADPKD independently of volumes. KEY POINTS: •The accuracy of ultrasonography for renal volume measurement increases by changing the classical ellipsoid formula. •Renal resistive index measured by color Doppler ultrasonography is helpful for the management of autosomal dominant polycystic kidney disease. •The role of Doppler US in autosomal dominant polycystic kidney disease should increase as a result of our findings.
