The impact of trimethoprim-sulfamethoxazole as Pneumocystis jiroveci pneumonia prophylaxis on the occurrence of asymptomatic bacteriuria and urinary tract infections among renal allograft recipients: a retrospective before-after study

Table 5 Univariable and multivariable Cox regression analysis for developing AGPN within one year after transplantation according to TMP-SMX prophylaxis administration

	Outcome AGPN	P value
	HR (95 % CI)	P value
TMP-SMX: univariable model (a)	1.46 (0.78–2.73)	0.239
TMP-SMX: first multivariable model (b)	1.12 (0.57–2.21)	0.751

a: Univariable model: adjusted for only TMP-SMX use
b: First multivariable analysis: adjusted for diabetes mellitus, subtype of immunosuppressive therapy and indwelling urological catheters. Since indwelling urological catheters were the only risk factors for AGPN no second multivariable analysis has been performed
