Post-surgical infection in elective cardiac surgeries: what is the role of dental evaluation? A retrospective 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
objectiveTo evaluate the prevalence and clinical characteristics of post-surgical infections after coronary and/or valvular heart surgery at a tertiary hospital and to examine the relationship between these infections and prior dental evaluation.
methodsA retrospective study was conducted among patients who underwent elective cardiac surgery at InCor-HCFMUSP between January 2018 and April 2019.
resultsThe sample included 1,276 surgeries, of which 10.6% were associated with post-surgical infection. Length of hospital stay and infection-related mortality differed significantly between patients with and without post-surgical infection (p<0.0001). Surgical site infections were the most prevalent infections, accounting for 6.2% of the sample, whereas pneumonia was the least frequent, accounting for 0.2%. Dental evaluation was performed in 62.3% of patients in the Valve Surgery Group and 25.8% of those in the Coronary Surgery Group. Among patients who underwent dental evaluation, 89.8% did not develop infection; dental evaluation was also significantly associated with length of hospital stay in the Valve and Coronary Surgery Groups (p=0.0187 and p=0.0317, respectively).
conclusionPost-surgical infection occurred in 10.6% of surgeries. Prior dental evaluation was not significantly associated with post-surgical infection, although a favorable percentage trend was observed among evaluated patients. Poor oral health is a risk factor for certain infections; however, these infections were not frequent in this sample. Hospital stay was shorter among patients who underwent dental evaluation.
