20 The primary outcome variable was change in diastolic blood pressure from the baseline screening visits to the average of the midpoint and closing visits. Patients who withdrew from the study after the midpoint were included in the primary analysis. Blood pressure for each subject at baseline, midpoint, and closing was the average of nine measurements (three measurements on each of 3 days). The trial was designed to have at least 80% power to detect a change in blood pressure of 3 mm Hg diastolic with two-sided P<.05. The actual sensitivity of the trial for the effect of each cation combination was determined from the 95% confidence intervals of the differences in the blood pressure changes between supplement and placebo groups (for an example, see “Show”). Multiple regression analyses determined the effect of each treatment compared with placebo using treatment group as an independent variable. Additional analyses were conducted on systolic blood pressure and on the changes at midpoint and closing, separately. Covariates were added to the multiple regression model to assess the effects of treatment in various subgroups of the patients, eg, baseline urinary electrolyte excretion. The model included treatment group, baseline urinary excretion, and the interaction term, treatment?urinary excretion. The effects of the treatments were also examined in subgroups with urinary electrolyte excretion levels above and below the median.

Results

The newest 125 people exactly who form the main data group complete on the very least the fresh new midpoint blood circulation pressure proportions. Seven clients were taken regarding trial on account of good diastolic blood circulation pressure >102 mm Hg (seven ahead of and you may step 1 adopting the midpoint dimensions); 2 of these have been choosing placebo, step three was in fact getting calcium and you may potassium, 2 was indeed getting potassium and you may magnesium, and 1 was acquiring calcium supplements and magnesium. Eight customers left the demonstration private explanations through to the midpoint hookup near me Orlando, and you will 5 additional patients leftover in advance of bringing closure measurements. There have been 82 (66%) guys and you can 43 (34%) women; 81 (65%) have been light, 34 (27%) was in fact black colored, cuatro (3%) had been Hispanic, and you may 6 (5%) was in fact Far eastern. Its mean decades try 53 years (range, 25 to help you 66 years) (Dining table step one ). One to diligent throughout the calcium supplements and you will magnesium category, step 1 patient on potassium and you will magnesium class, and you will nothing throughout the almost every other a couple teams got prior to now pulled antihypertensive medication.

There have been no extreme distinctions among the many medication communities from inside the gender, battle, many years, bmi, otherwise smoking (Dining table 1 )

On standard, suggest everyday dieting intake was 782±477 milligrams (19±thirteen mmol) calcium, 284±79 milligrams (12±5 mmol) magnesium, and you can 2770±802 milligrams (77±thirty-two mmol) potassium. Advertised intake of all about three nutrition and additionally of energy had a tendency to fall off averagely inside demo in all organizations which have no factor one of several five groups (Desk dos ). Baseline urinary removal out of calcium, magnesium, and you can potassium is actually comparable over the four procedures organizations (Desk step 3 ). Urinary removal regarding calcium supplements increased significantly on the a couple organizations who received calcium when comparing to the new placebo class. In addition, potassium removal increased significantly in the a couple organizations whom acquired potassium supplements, and magnesium excretion more than doubled regarding calcium supplements and you will magnesium group (Dining table 3 ). The rise for the magnesium excretion regarding the potassium and you will magnesium category didn’t go statistical value. Based on pill matters, the brand new patients grabbed everything 95% of their tasked pills regarding the trial.

Mean blood pressure levels at standard try 139±12 mm Hg systolic and you will 90±cuatro mm Hg diastolic on the customers whom complete the latest demo and you can is actually comparable among five groups (Table 4 ). Blood pressure level decreased significantly by less than six mm Hg from inside the new organizations assigned to placebo, potassium and you will magnesium, and you can calcium and potassium, while the fresh new blood pressure level reduced the latest calcium supplements and you can magnesium group, approximately step one mm Hg, is nonsignificant. There are zero tall differences in change in blood pressure level anywhere between for every single cures group and the placebo classification. The outcomes have been unchanged by modifying the blood pressure level distinctions having nonsignificant inaccuracies within the baseline properties, together with dietary consumption and you will urinary electrolyte excretion.
