Magnesium-L-threonate improves sleep quality and daytime functioning in adults with self-reported sleep problems: A randomized controlled trial.

Comparing activity daily movement score, MgT approached significance at day 7 (p = 0.059) and was significantly improved at day 14 (p = 0.035) and day 21 (p = 0.044) over placebo.

In most of the measurements using questionnaires, both MgT group and placebo group showed a statistical significance over the baseline (as evidenced by the significant p values of condition and time separately) but failed to reach significance when compared between MgT and placebo (as evidenced by the p value of the interaction).

Nonsignificant improvements (i.e., trending in the right direction) were evidenced for the MgT compared to the placebo for most other LSEQ and RSQ parameters; they did not reach statistical significance, apparently due to the strong placebo effects that is often associated with subjective measures.
