Table 2. Metaregression of weight changes per period in drug-naive patients.

The coeffecient indicates the changes of weight compared with the constant (period 1).
*constant is period 1 that serves as reference in change.
Data in italics indicate 95% confidence interval.
The outcome in bold indicate significant difference in weight change of reference category.
