Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention: 3 grams of Calcium ß-Hydroxy-ß-Methylbutrate (HMB-Ca) dissolved in either 150ml of orange juice for those allowed oral intake or 150ml of water for those being enterally fed.

The intervention/ control will be administered by a nurse once daily over hospital admission from day 1 post enrollment until day 28 or hospital discharge. Consumption of the intervention/placebo will be monitored daily through nursing administration records in the medication administration records.

In a sub-group of patients who do not meet additional exclusion criteria and whose medical treatment decision maker (MTDM) provide consent, a muscle biopsy and plasma sample will be collected on day 1 post enrollment and again at day 7 post enrollment.

Statistical methods / analysis
A convenience sample has been used to determine the primary aim to estimate the feasibility of adequate recruitment and the ability to perform proposed outcome measures in this patient cohort.
Descriptive statistics and tables will be used to summarize relevant patient demographics and outcomes overall and according to the two treatment groups. Continuous data will be reported as means (with standard deviations) if approximately normally distributed, and medians (inter-quartile range) and full [range] otherwise. Categorial data will be reported as frequencies and summarized as proportions with 95% confidence intervals as appropriate.
Differences between the two treatment groups will be analysed using the two-sample unpaired t-test for approximately normal data, the Wilcoxon-rank sum test for substantially skew data and the Fisher’s exact test for categorical variables within contingency tables. Group differences for the change weight, muscle mass, and muscle strength from baseline to day 90 enrollment will be compared after adjustment for initial baseline values and other selected potentially relevant co-variables using linear regression (analysis of covariance, ANCOVA). Statistical significance will be set conventionally at a p value of 0.05. Given the clinical severity of the critical care trauma patients under study, deaths prior to recruitment and during the study are likely, both of which form of patient losses may influence the statistical validity of the observed outcomes in the study cohort. In the presence of sufficient data, exploratory time-to-event analyses in competing-risks regression models returning subhazard functions of failure events of primary interest while accounting for the competing outcome of death will be explored according to the method of Fine and Gray (1999). Multiplicity of testing will be acknowledged but multiple statistical tests will be otherwise unadjusted, consistent with the exploratory nature of this pilot study. Data analyses will be carried out using the Statistical Package for the Social Sciences (IBM® SPSS® Statistics Premium Grad Pack Version 25.0) or Stata Corporation (Stata Statistical Software: Release 16. College Station, TX: StataCorp LP; 2019).
