Table 4. Paper-tablet discrepancies and device attributable coding errors with reference to residency status.

Discrepancies & Type of error	Urban (n = 47)		Rural (n = 48)		p-value
	Mean	%	Mean	%
Discrepancies	9.40	4.02	12.83	5.48	0.0004
Paper errors	4.06	1.74	5.29	2.26	0.06
Tablet errors	4.21	1.80	5.08	2.17	0.12
Both paper and tablet errors	0.45	0.19	0.42	0.18	0.85
Unattributable errors	0.68	0.29	2.04	0.87	NA

n: number of interviews.

%: Percentage of errors with reference to 234 comparison fields. p-value: Simple mixed binomial regression model with factor research assistant team.

NA: Not applicable.

The difference between the means of paper errors and tablet errors for urban and rural interviews is statistically insignificant. Paired t-test p-values for urban and rural setting are 0.83 and 0.75 respectively.
