Urinalysis Accuracy for Diagnosis of Bacteremic Urinary Tract Infections in 0-3-Month-Old Infants.

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
aimTo assess urinalysis (UA) accuracy for the diagnosis of bacteremic urinary tract infections (UTI) in young infants.
methodsA multi-center retrospective study collecting 2008-2022 data of infants 0-3-month-old with bacteremic UTI (same pathogen in urine and blood).
resultsOf 110 infants with bacteremic UTI, 64% were male and the median age was 21 days; 85% were ≤ 2 months of age. Fever ≥ 38°C was evident in 80% and 2% had hypothermia. Gram-negative bacteria were cultured in 96%, E. coli in 72%, and Klebsiella in 18%. A total of 19 of the 110 infants (17%) had a normal UA (negative leukocyte esterase and negative nitrites). The sensitivity of abnormal UA for UTI diagnosis was 83% (95% confidence interval 76%-90%); 95% of the normal UA group had Gram-negative pathogens: E. coli in 58% and Klebsiella in 26%. In comparing infants with abnormal and normal UA, no differences in age, sex, rate of febrile infants, and pathogens were noted.
conclusionsThe accuracy of UA for identification of 0-3-month-old infants with bacteremic UTI is limited. Bacteremic UTI with a normal UA occurred in both genders, various ages, and pathogens. Relying solely on UA for ruling out UTI in 0-3-month-old infants may lead to significant underdiagnosis with a potential increase in morbidity.
