Event colorectal adenoma

Compared with controls without polyps, incident adenoma cases were more likely to be male, smokers, physically inactive, have higher body mass index, and have higher intake of energy, but had lower intakes of calcium, magnesium and vitamin D (Table 1). However, intakes of calcium between 1200 mg and 1600 mg per day were associated with a significantly reduced risk of incident adenoma with an OR of 0.82 (95% confidence intervals (CI): 0.68–0.97) when compared with calcium intake between 600 and 1200 mg per day (referent group). When analyses were limited to incident advanced and/or synchronous adenomas, the inverse pattern of associations was found with a corresponding OR of 0.71 (95% CIs: 0.52–0.96) for calcium intake between 1200 and 1600 mg. When these analyses were stratified by the Ca:Mg ratio, the dose–response between calcium intake and advanced and/or synchronous adenoma were only observed in participants with a Ca:Mg ratio between 1.7 and 2.5 (P-_trend, 0.05). The number of cases in the Ca:Mg ratio < 1.7 strata was too small to make meaningful statistical inference. There was no statistically significant telecommunications between calcium and the Ca:Mg ratio (P-_interaction: 0.11).

Metachronous (recurrent) adenoma

Compared with members instead of metachronous adenoma, metachronous adenoma cases had been in addition to expected to feel men and over weight, in order to enjoys highest complete opportunity consumption but lower calcium supplements consumption (Dining table step 1). Metachronous adenoma times was indeed less likely to be white and also to has genealogy from CRC.

We don’t to see any mathematically tall connections anywhere between calcium consumption and metachronous adenoma (Dining table step 3). Connectivity have been exactly the same whenever analyses had been separated by strata out of California:Mg consumption proportion (Dining table step three), state-of-the-art adenoma or parallel adenoma (Desk step three), area from adenoma (i.age., distal otherwise proximal, study perhaps not revealed) and you may baseline adenoma characteristics (i.age., advanced/parallel adenoma) (Supplementary Desk step 1).
