Hemoglobin A1c as a Predictor of Surgical Site Infection in Patients With Orthopaedic Trauma.

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
introductionPrevious research involving diabetes mellitus (DM), glycemic control, and complications in orthopaedic patients has primarily focused on elective procedures. The purpose of this study was to evaluate hemoglobin A1c (A1c) as a predictor of postoperative surgical site infection (SSI) in patients with orthopaedic trauma.
methodsPatients aged 18 years or older treated surgically for an acute fracture by a fellowship-trained orthopaedic trauma surgeon at a single academic tertiary referral center with a laboratory value for A1c available within 3 months of their surgery were identified retrospectively. Postoperative SSI was defined according to 'Fracture related infection: A consensus on definition from an international expert group,' by Metsemakers et al.
resultsA total of 925 patients met criteria for analysis. A receiver operating characteristic curve was calculated using A1c as a predictor for signs suggestive and confirmatory of SSI and demonstrated an area under the curve of 0.535 and 0.539, respectively. No significant difference was found in the rate of signs suggestive or confirmatory of SSI in patients with normal A1c levels (<6.5) compared with patients with A1c levels consistent with a diagnosis of DM (>6.5), P-value = 0.199 and P-value = 0.297, respectively. No significant difference was found in the rate of signs suggestive or confirmatory of SSI in patients with completely uncontrolled DM (A1c > 10) compared with patients with A1c levels <10, P-value 0.528 and P-value = 0.552, respectively.
conclusionExisting literature has demonstrated an association with postoperative infection in orthopaedic patients who have elevated A1c values. In this cohort of patients with orthopaedic trauma, hemoglobin A1c was not a valuable tool to predict postoperative SSI. Given these findings, routine A1c monitoring is not a reliable predictor of SSI criteria in patients with orthopaedic trauma based on the current consensus definition of SSI in fracture surgery.
