Table 4 Changes in body composition and biological parameters from baseline to 9 weeks in both groups

From: Daily consumption of ready-to-use peanut-based therapeutic food increased fat free mass, improved anemic status but has no impact on the zinc status of people living with HIV/AIDS: a randomized controlled trial
