Age-specific and sex-specific weight gain norms to monitor antiretroviral therapy in children in low-income and middle-income countries

Viral load and CD4% are often not available in resource-limited settings for monitoring children's responses to antiretroviral treatment (ART). We aimed to construct normative curves for weight gain at six-, twelve-, eighteen-, and twenty-four-month post initiation of ART in children, and to assess the association between poor weight gain and subsequent responses to ART
