text: Yo, check it out, in this study we aimed to peep
  The effects of CGM on blood glucose levels, keep it deep
  Body weight, blood pressure, hypoglycemia, we analyzed
  Type 2 diabetes patients, randomized trials, no surprise
  
  We hit up MEDLINE, Cochrane Controlled Trials Registry too
  ClinicalTrials.gov, we searched through and through
  Selected RCTs with CGM, type 2 diabetes patients in the mix
  Now let's break it down with some statistical tricks
  
  Standardized mean difference, risk ratio, we calculated it all
  With a random effects model, the numbers won't fall
  Seven RCTs, 669 patients, that's what we found
  They met our criteria, into the meta-analysis they're bound
  
  Compared to self-monitoring, CGM came through
  HbA1c levels dropped, that's what it do
  SMD negative 0.35, CI minus 0.59 to minus 0.10
  P-value 0.006, yo, that's the trend we've sent
  
  Time spent with hypoglycemia got shorter, that's a win
  SMD negative 0.42, CI from minus 0.70 to minus 0.13, come on in
  P-value 0.004, CGM got it in control
  But hold up, no diff in body weight and blood pressure, that's the whole
  
  So, CGM for type 2 diabetes can bring the heat
  Lower HbA1c levels, less time with hypoglycemia, it's sweet
  But yo, we gotta be careful, few RCTs in sight
  And heterogeneity, so take the results in stride
