Clinical Urinary Tract Infections in Kidney Transplant Recipients With Initially Asymptomatic Bacteriuria: A Single-Center Retrospective Cohort Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Rationale & Objective: Management of asymptomatic bacteriuria in kidney transplant recipients remains uncertain. Our main objective was to evaluate whether patient- or episode-related factors could help identify episodes of asymptomatic bacteriuria associated with a higher risk of being followed by a symptomatic urinary tract infection. Study Design: A single-center, retrospective cohort study. Settings & Participants: Consecutive patients who received a kidney transplantation between January 1, 2008, and April 26, 2016, and experienced ≥1 episode of asymptomatic bacteriuria during the first 3 years posttransplantation. Exposure: Recipient age, sex, diabetes, donor type, retransplant, urological abnormalities, thymoglobulin for induction, time since transplant, presence of ureteral stent, prior acute rejection, leukocyturia, hematuria, urinary nitrites, bacterial strain, prior urinary tract infection, resistance to antibiotics, antibiotic treatment. Outcomes: The primary outcome was the occurrence of symptomatic urinary tract infection. The secondary outcome was antibiotic treatment of asymptomatic bacteriuria. Analytical Approach: A Cox regression survival analysis model accounting for recurrent events and a logistic regression model. Results: From a cohort of 508 patients, we included 597 episodes of asymptomatic bacteriuria detected in 119 outpatients. Antibiotics were prescribed in 26% of these episodes. Overall, 56 (9%) of episodes were followed by a symptomatic urinary tract infection. Pretransplant diabetes (hazard ratio [HR], 4.28; 95% confidence intervals [CI], 2.40-7.61), leukocyturia or hematuria (HR, 2.24; 95% CI, 1.27-3.96), and the presence of a ureteral stent (HR, 3.40; 95% CI, 1.33-8.70) were associated with development of a clinical urinary tract infection in patients with asymptomatic bacteriuria. Limitations: The small number of events limits complete multivariable adjustment. It also prevents us from drawing a definite conclusion about the importance of a number of independent variables as risk factors for the outcome. Conclusions: The benefit of treating episodes of asymptomatic bacteriuria with high-risk characteristics should be investigated in future trials.
