1 · What the graph read from it

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.

2 · The registry

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

Background: Extracapsular hip fractures comprise approximately half of all hip fractures and the incidence of hip fractures is exponentially increasing. Extramedullary fixation using a dynamic hip screw (DHS) has been the gold standard method of operative treatment for unstable extracapsular fractures, however, in recent years, intramedullary nails (IMN) have become a popular alternative. IMN versus DHS is continuously discussed and debated in literature. Therefore, the purpose of this systematic review and meta-analysis is to directly compare the peri- and post-operative outcomes of these two techniques to provide an up-to-date analysis of which method of fixation is superior. Methods: The MEDLINE/PubMed, Embase and Web of Science Database were searched for eligible studies from 2008 to April 2022 that compared peri- and post-operational outcomes for patients undergoing IMN or DHS operations for fixation of unstable extracapsular hip fractures (PROSPERO registration ID:CRD42021228335). Primary outcomes included mortality rate and re-operation rate. Secondary outcomes included operation time, blood loss, transfusion requirement, complication, and failure of fixation rate. The risk of bias and quality of evidence were assessed using the Cochrane RoB 2.0 tool and GRADE analysis tool, respectively. Results: Of the 6776 records identified, 22 studies involving 3151 patients were included in the final review. Our meta-analysis showed no significant differences between mortality rates (10 studies, OR 0.98; 95% CI 0.80 to 1.22, p = 0.88) or re-operation rates (10 studies, OR 1.03; 95% CI 0.64 to 1.64, p = 0.91) between the two procedures. There were also no significant differences found between complication rates (17 studies, OR 1.29; 95% CI 0.79 to 2.12, p = 0.31) and failure of fixation rates (14 studies, OR 1.32; 95% CI 0.74 to 2.38, p = 0.35). However, DHS operations had a significantly longer operation time (p < 0.0001) and blood loss (p < 0.00001) than IMN operations. Conclusion: Overall, based on the outcomes assessed, this review has demonstrated that there is no significant difference in the post-operative outcomes for DHS vs IMN, however a significant difference exists in two of the intraoperative outcomes assessed in this review.
