Measuring malaria diagnosis and treatment coverage in population-based surveys: a recall validation study in Mali among caregivers of febrile children under 5 years

Table 6 Inflation factor (IF) including 95% confidence intervals for each of the main recall indicators, across all sites and by type of site

	All sites	Public urban	Public rural	CHWs	Private urban
Recall of finger/heel stick	1.06	1.01	1.12	1.05	1.35
Recall of positive malaria test result^a	1.11	1.11	1.05	1.23	0.92
Recall that malaria diagnosis was made	0.82	0.86	0.66	1.00	0.82
Recall of any anti-malarial given^b	0.64	0.65	0.60	0.63	0.69
Recall of ACT given^b	0.53	0.51	0.51	0.62	0.47
Recall of ACT, corrected by visual aid	0.87	0.85	0.95	0.94	0.68
Recall of ACT, corrected by retained prescription	0.99	1.08	1.12	0.84	0.90
Recall of ACT, corrected by retained packaging	1.02	1.06	1.01	1.03	0.95
Recall of ACT, corrected by visual aid, prescription or retained packaging	1.20	1.26	1.28	1.17	1.09

A population-level bias is generally considered to be low if 0.75 < IF < 1.25; moderate if 0.5 < IF < 1.5; and high if IF < 0.5 or IF > 1.5, based on recommendations from the Child Health Epidemiology Reference Group (CHERG) and Improving Coverage Measurement (ICM) group
