1 Values were mean intakes (SD) for 4 days observation except in BBC in September/October when n = 3. WF was the unit of measurement by which all subjects were apportioned their intake from the communal feeding bowl. For other information on compounds see Table 1;
2 Values shown are geometric means (SD) for men and women 15 to 49 years in the respective compounds (see Table 1);
3 Data were log transformed before repeated measures ANOVA and subsequent group tests; seasonal differences are shown where mean values do not share a common superscript letter (a,b,c) (P < 0.05, LSD test);
# Gender differences found within the compound (P < 0.05, LSD test);
xx Differences between compounds (P < 0.05, LSD test).
