Factors associated with humeral shaft fracture nonunion.

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
purposeThis study aims to describe factors associated with risk of nonunion in patients treated for humeral shaft fracture.
methodsAdult patients treated for humeral shaft fracture at one Level 1 center from December 2009-July 2020, screened via ICD-10 code were retrospectively reviewed. Patient characteristics and radiographic analysis were recorded. Independent samples t-test was used for continuous variables, and chi squared or fishers exact test for categorical. P < 0.05 was considered significant.
resultsOf 386 patients, 15.3% went onto nonunion (mean time to diagnosis 122 days). Patients with nonunion were more likely have comorbid alcoholism (p < 0.001) and hypothyroidism (p 0.048) and were significantly more likely to have been initially managed nonoperatively (p < 0.001). Mechanism was significantly associated (p 0.008). Of those with nonunion treated surgically initially, there were differences in the number and positioning of screws utilized in ORIF, including more screws distally (4.29+/− 1.86 vs. 3.77+/− 0.92, p 0.048) to the fracture through the plate, and fewer screws outside of the plate in the form of lag screws (0.41+/− 0.87 vs. 1.13+/− 1.44, p 0.045) in diagnosed nonunion. 11 patients diagnosed with nonunion required more than 1 revision procedure (mean 2.18). 27 patients diagnosed with nonunion had available documented radiographic union (range 56–872 days from date of nonunion diagnosis).
conclusionSpecific comorbidities, initial nonoperative management and surgical construct configuration in patients treated with ORIF are risk factors for development of humeral shaft fracture nonunion. Treatment and recovery from humeral shaft nonunion remain varied, warranting further study.
