Risk Factors for Postoperative Urinary Tract Infection in Patients Undergoing Arthrodesis for Spinal Deformity of Different Levels.
Article in International journal of spine surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundWhile studies have identified urinary tract infection (UTI) as a complication after spine fusion, UTI is understudied in the context of fusion for spinal deformity. This study sought to determine both UTI incidence after multilevel posterior fusion for spinal deformity and whether pooled risk factors (RFs) increased UTI risk.
methodsPatients who had posterior fusion for spinal deformities between 2010 to 2019 were queried from the PearlDiver database, separated by the number of levels operated on (<7, 7-12, and >12), matched for age/gender, and analyzed for UTI incidence within 1 week and 1, 2, and 3 months. Any patient with a note of diabetes, obesity, rheumatoid arthritis, or coronary artery disease within 1-year prior to surgery and who contracted UTI within 1 month after fusion was included in the RF group for each level span. Patients of each level span with any RF were compared with those without any RFs.
resultsA total of 20,893 patients underwent posterior fusion for spinal deformities from 2010 to 2019. After matching, each level set had 2239 patients. At 1, 2, and 3 months, the >12 levels subgroup showed statistically higher UTI incidence than the 7 to 12 and <7 levels subgroups. At 3 months, UTI was similar between the <7 and 7 to 12 subgroups, with 3.8% and 3.9%, respectively (
conclusionsDiabetes, obesity, rheumatoid arthritis, and coronary artery disease were associated with a higher risk of UTI after posterior fusion for spinal deformity for all level sets. patients who underwent procedures for more than 12 levels had the highest rate of UTI. This is the first study to analyze and compare UTI incidence following fusion for spinal deformity. LEVEL OF EVIDENCE: 3:
