Forest plot of the data from random effects meta-analysis shown as mean difference with 95% confidence intervals on insulin homeostasis outcomes, fasting glucose, fasting insulin, insulin resistance (HOMA-IR), for the studies that presented data concerning these parameters. Data are presented according to time-restricted fasting (TRF) and the metabolic conditions: healthy or disease condition, obesity, T2D or MetS. For each study, the square represents the mean difference between baseline and fasting conditions, with the horizontal line intersecting it as the lower and upper limits of the 95% confidence interval [7,19,20,24,30,35,46,51,56,58].
