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

The association between vitamin D and thyroid cancer is unclear. It is unknown if CYP27A1 or CYP2R1 are present in normal thyroid or cancer cells and there is limited information regarding response to treatment with vitamin D. SV40 immortalized follicular cells (N-thy) and six thyroid cancer cell lines were treated with 10 µM vitamin D(3), 0.1 µM 1,25(OH)(2)D(3) or vehicle × 24 h. CYP27A1, CYP2R1, CYP27B1 and CYP24A1 mRNA were measured using quantitative real-time-PCR before and after treatment. Cell proliferation was also evaluated in TPC1 and C643 cells after treatment with D(3), 25(OH)D(3) and 1,25(OH)(2)D(3). Baseline CYP27A1 and CYP27B1 mRNA were present in all cells, CYP2R1 was higher and CYP24A1 mRNA was lower in cancer cell lines versus N-thy. TPC1 cells had increased CYP24A1 mRNA levels when treated with both D(3) (3.49, p < 0.001) and 1,25(OH)(2)D(3) (5.05, p < 0.001). C643 cells showed increased CYP24A1 mRNA expression when treated with 1,25(OH)(2)D(3) (5.36, p < 0.001). D(3), 25(OH)D(3) and 1,25(OH)(2)D(3) all significantly decreased cell proliferation in TPC1 and C643 cells. Overall, both cancerous and N-thy cell lines express CYP27A1 and CYP2R1 in addition to CYP27B1, establishing the potential to metabolize D(3) to 1,25(OH)(2)D(3). Additionally, vitamin D(3), 25(OH)D(3) and 1,25(OH)(2)D(3) all had an antiproliferative effect on two thyroid cancer cell lines.
