Is a Fracture of the Transverse Process of L5 an Indicator of the Presence and/or Severity of a Pelvic Fracture?

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
introductionA transverse process of L5 (L5TP) fracture may be associated with the presence and/or severity of a pelvic fracture. However, there is little evidence to support this view. The purpose of this study was to investigate the relationship between L5 TP fracture and the presence and/or severity of a pelvic fracture on radiograph and CT.
methodsA total of 146 patients (82 women and 64 men; age range, 5-97 years) who were treated for pelvic fractures were evaluated. The site of pelvic fractures, presence of an L5 TP fracture with radiograph and CT, associated injuries and the need for blood transfusion, surgical intervention, and mortality were investigated retrospectively. According to the Burgess and Young classification, there were 42 unstable fractures. For each parameter, correlations between the parameters were evaluated using a chi-squared test and a logistic regression analysis. A p-value <0.05 was considered to be statistically significant.
resultsThe sensitivity of L5 TP fractures on radiograph and CT were 51% and 95%, respectively (p < 0.0001). Multiple logistic regression analysis revealed that, of the L5 TP fractures patients on radiograph, the odds ratios for sacral fractures were 4.5 (95% confident interval [CI], 1.1-17.9); based on CT, the odds ratios for sacral fractures and the need for blood transfusion were 18.2 (95%CI, 5.1-64.9) and 3.2 (95%CI, 1.1-9.1), respectively.
conclusionsThis study demonstrated that L5 TP fractures on radiograph and/or CT could indicate a high risk of sacral fracture and need for blood transfusion. When an L5TP fracture is diagnosed on initial radiograph or CT in the emergency setting, it is necessary to conduct further investigations for pelvic ring fractures and to alert the attending staff to the high-risk fracture.
