Table 1.

The partial receiver operating characteristic values (pROC) obtained from diseases ensemble models, resulting from socioeconomic (S) and environment only (E) sets of variables

	Socioenvironmental			Environment only			Comparison (S-E)
	Mean AUC	Mean pROC ratio at 5%	P value	Mean AUC	Mean pROC ratio at 5%	P value	Change in pROC (%)
Hantavirus	0.88	1.56	0.00	0.89	1.43	0.00	9%
Leptospirosis	0.78	1.28	0.00	0.74	1.10	0.00	16%
Schistosomiasis	0.87	1.48	0.00	0.85	1.41	0.00	5.19%
Dengue fever	0.74	1.27	0.00	0.66	1.07	0.00	18.8%
Malaria	0.72	1.17	0.00	0.56	1.03	0.02	14%
Acute Chagas disease	0.89	1.37	0.00	0.82	1.35	0.00	1.73%
Leish. Visceral	0.80	1.34	0.00	0.77	1.31	0.00	2.1%
Leish. Cutaneous	0.71	1.23	0.00	0.64	1.08	0.00	13.1%
Brazilian spotted fever	0.95	1.72	0.00	0.94	1.74	0.00	−1.1%
Average	–	1.40	–	–	1.30	–	10%

All models performed better than random. The bold italic value symbolizes the only disease, Brazilian spotted fever, in which the addition of socioeconomic variables in the model lowered model predictability

pROC: Partial receiver operating characteristic; AUC: Area under the curve metric; S: Models made socioenvironmental set of variables; E: Models made with environmental set of variables; –: Not applicable
