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

Recently reported findings from major clinical trials show no cancer protection from vitamin D supplementation, and results from observational studies of vitamin D in cancer prevention are inconsistent. There is a need for new hypotheses to guide investigations of the controversies surrounding vitamin D supplementation and cancer. Bioactive vitamin D, 1,25(OH)2D, is an endocrine factor that regulates phosphate homeostasis by increasing dietary phosphate intestinal absorption. When phosphorus serum levels are high, as in hyperphosphatemia, an endocrine feedback mechanism lowers bioactive vitamin D which reduces intestinal phosphate absorption. Low vitamin D levels have been associated with cancer incidence, and tumorigenesis is associated with high levels of dysregulated phosphate in the body. In this mini-review, the author hypothesizes that hyperphosphatemia may be an intermediating factor in the association of lowered vitamin D levels and increased risk for tumorigenesis. Furthermore, this article challenges the UVB-vitamin D-cancer hypothesis which proposes that reduced cancer incidence at lower geographic latitudes is related to high levels of vitamin D from UVB exposure. The author proposes that reduced phosphorus content and availability in tropical and subtropical soil, and lower dietary phosphate intake from consumption of tropical and subtropical crops (as in the Mediterranean diet), may mediate the association of reduced cancer risk with lower latitudes.
