6. Dietary advice versus dietary advice plus oral nutritional supplements: outcomes with additional data provided or imputed.

Study ID	Outcomes where the author provided data	Outcomes where data were imputed
Arnold 1989		Weight read from a graph and SD of change derived by imputation
Baldwin 2011	Mortality, weight, grip strength, QoL scores
Burden 2011	Energy intake, protein intake
Burden 2017	Energy intake, protein intake, weight, grip strength
de Luis 2003	Energy intake, weight, MUAC, TSF	SD of change in FFM imputed from the study by Campbell 2008
Diouf 2016	Weight, FFM, body fat, BMI
Fuenzalida 1990		SD of change in weight, TSF, MAC derived by calculation from reported P values
Gonzalez‐Espinoza 2005	Energy intake, weight, MAC, MAMC	SD of change in BMI derived by imputation from Sharma 2002a. SD for TSF imputed using a correlation coefficient of 0.8
Huynh 2015	Weight, BMI, grip strength, energy intake, protein intake
Kapoor 2017	Weight, QoL scores, energy intake, protein intake, MUAC
McCarthy 1999	Energy & protein intake
Murphy 1992		SD of change in weight & energy intake calculated from reported P values
Norman 2008b	Weight, MAMC, TSF	Data on body cell mass were used in the analysis of FFM and combined using the SMD
Sharma 2002a		SD of change in weight and BMI calculated from reported P values for one intervention group and then used to impute the SD of change for the second intervention group. Duplicate IDs have been used to include the two groups in the analysis.

SD: standard deviation; BMI: body mass index; FFM: fat‐free mass; MAMC: mid‐arm muscle circumference; MAC: mid‐arm circumference; MUAC: mid‐upper arm circumferences; QoL: quality of life; TSF: triceps skinfold thickness. format?
