Undereporting of acute pesticide poisoning in Tanzania: modelling results from two cross-sectional studies

Table 2 Sensitivity analysis of APP rates^a per 1000000 by circumstances under different redistribution allocations for ‘unknown’ circumstances

Circumstance	n	%	Baseline rate per 1,000,000	APP Rates per 1,000,000 under different scenarios
Circumstance	Circumstance data table	% by circumstance	No Redistribution	(a) all unknown to Suicide	(b) all unknown to Accident/Homicide	(c) all unknown to Occupational	(d) unknown redistributed equally^b to other categories	(e) unknown allocated proportionally^c to other categories
(a) Unknown	44	19.13	2.74	0.00	0.00	0.00	0.00	0.00
(b) Suicide	108	46.96	6.71	9.45	6.71	6.71	7.63	8.30
(c) Accidental/ homicide	59	25.65	3.67	3.67	6.41	3.67	4.58	4.54
(d) Occupational	19	8.26	1.18	1.18	1.18	3.92	2.09	1.46
Total	230	100.00	14.30	14.30	14.30	14.30	14.30	14.30
Sum of circumstances other than occupational (a + b + c)			13.12	13.12	13.12	10.38	12.21	12.84

^a The baseline rates were obtained in a prospective follow-up of 10 facilities in four regions of Tanzania over 12 months in 2006
^bThe 44 cases of APP were allocated in equal proportion to suicide, occupational circumstances and accident/homicide
^cThe 44 cases of APP with were allocated in proportion to the baseline rates of APP for suicide, occupational circumstances and accident/homicide (6.71: 1.18: 3.67, respectively)
