Review in Seminars in nephrology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 papers, 1 of them a synthesis that pooled it.

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

Decline in renal function is related directly to cardiovascular mortality. However, traditional risk factors do not fully account for the high mortality in these patients. Activated vitamin D, a hormone produced by the proximal convoluted tubule of the kidney, appears to have beneficial effects beyond suppressing parathyroid hormone (PTH). However, activated vitamin D also can cause hypercalcemia and hyperphosphatemia in chronic kidney disease. Newer agents such as vitamin D receptor activators (eg, paricalcitol) suppress PTH with reduced risk of hypercalcemia and hyperphosphatemia. Recent evidence from animal and preliminary human studies supports an association between vitamin D receptor activators and reduced risk of cardiovascular disease deaths, irrespective of PTH levels. New pathways of vitamin D regulation also have been discovered, involving fibroblast growth factor-23 and klotho. Although considerable work has been performed to advance our understanding of the effects of vitamin D in health and chronic kidney disease, more investigations and randomized trials need to be performed to elucidate the mechanistic underpinnings of these effects.
