Hi There, you may look at this guidance from GNC https://www.nutritioncluster.net/resources/nutrition-humanitarian-needs-analysis-guidance-engfres 

For typical MAM PLW programming in TSFP (discharge only when infants reach 6 month), there should not be requiring any correction factor for the caseload estimation.

[Number of MAM PLW in need = MAM prevalence x population of PLW from
“Affected” areas]

Thanks,
