Table 4 Multivariate logistic regression for independent factors associated with total mg concentrations and clinical outcomes (n = 500).
Outcome tested in the model | Independent factors | aOR* [95% CI] | p-value |
|---|---|---|---|
Transfers to High Dependency Unit | Total Mg concentration | 4.34 [1.24–15.06] | 0.02 |
Frusemide | 3.09 [1.99–4.79] | < 0.01 | |
Cardiac arrest | Total Mg concentration | 14.64 [3.04–70.57] | < 0.01 |
Female | 0.48 [0.24–0.95] | 0.04 | |
Albumin mmol/L | 0.93 [0.88–0.96] | < 0.01 | |
Frusemide | 3.29 [1.61–6.72] | < 0.01 | |
6-month mortality | Total Mg concentration | 11.44 [2.46–53.17] | < 0.01 |
Albumin mmol/L | 0.89 [0.85–0.93] | < 0.01 | |
Frusemide | 1.91 [1.04–3.51] | 0.04 | |
Age | 1.03 [1.01–1.05] | < 0.01 | |
Hypermagnesemia verses Hypomagnesemia | Potassium, IQR, mmol/L | 1.73 [1.10–2.72] | < 0.01 |
Sodium, IQR, mmol/L | 1.07 [1.02–1.11] | < 0.01 | |
eGFR, IQR, ml/min/1.73 m2 | 0.96 [0.95–0.97] | < 0.01 | |
*Backward stepwise multi-regression model for an adjusted odds ratio (aOR) for the following relevant factors that includes total Mg concentrations, age, female, body mass index, diabetes, hypertension, chronic kidney disease, heart failure, potassium, sodium, creatinine, estimated glomerular filtration rate, albumin, frusemide, comorbidites ≥ 3, and Mg correction/treatment. | |||
