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

objectiveHypertension is associated with renal immune cell accumulation and sodium retention. Lymphatic vessels provide a route for immune cell trafficking and fluid clearance. Whether specifically increasing renal lymphatic density can treat established hypertension, and whether renal lymphatics are involved in mechanisms of blood pressure regulation remain undetermined. Here, we tested the hypothesis that augmenting renal lymphatic density can attenuate blood pressure in established hypertension.

methodsTransgenic mice with inducible kidney-specific overexpression of VEGF-D ('KidVD+' mice) and KidVD- controls were administered a nitric oxide synthase inhibitor, L-NAME, for 4 weeks, with doxycycline administration beginning at the end of week 1. To identify mechanisms by which renal lymphatics alter renal Na handling, Na excretion was examined in KidVD+ mice during acute and chronic salt loading conditions.

resultsRenal VEGF-D induction for 3 weeks enhanced lymphatic density and significantly attenuated blood pressure in KidVD+ mice whereas KidVD- mice remained hypertensive. No differences were identified in renal immune cells, however, the urinary Na excretion was increased significantly in KidVD+ mice. KidVD+ mice demonstrated normal basal sodium handling, but following chronic high salt loading, KidVD+ mice had a significantly lower blood pressure along with increased urinary fractional excretion of Na. Mechanistically, KidVD+ mice demonstrated decreased renal abundance of total NCC and cleaved ENaCα Na transporters, increased renal tissue fluid volume, and increased plasma ANP.

conclusionOur findings demonstrate that therapeutically augmenting renal lymphatics increases natriuresis and reduces blood pressure under sodium retention conditions.
