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

backgroundIntramedullary nails have become the main treatment for intertrochanteric fractures. However, a distal locking procedure during nailing gradually raised controversy. In this study, a systematic review and meta-analysis of clinical trials was performed to summarize existing evidence, aiming to determine the safety and efficacy of distal locking or unlocking in the nailing of stable intertrochanteric fractures.

methodsAppropriate articles were identified using the most common public databases, such as PubMed, Embase, the Cochrane Library, and Google Scholar from the inception of each database to April 2019, without restriction of language, publication date, and considering ongoing trials. Eligible studies were represented by randomized controlled trials or retrospective cohort studies, comparing distal locking and unlocking for the treatment of acute stable intertrochanteric fractures in adult patients. Information regarding methodological quality, patient demographics, and clinical outcomes were extracted independently by two reviewers. Subsequently, patients were divided into a locking and unlocking group.

resultsThis study included 9 articles, comprising a total of 1978 patients with a similar baseline. The results showed that the unlocking group had a shorter operation time, less intraoperative bleeding, lower transfusion rate, and less thigh pain after the treatment of femoral intertrochanteric fracture when compared with the distal locking group. No significant differences were observed in safety-related outcomes, including mortality, infection rate, cutting out, loss of reduction, backing out of lag screws, cephalic screw breakage, nail breakage, and peri-implant fractures between the two groups. In addition, efficacy-related outcomes including nonunion, delayed healing rates, and the Harris functional score were not significantly different between the two groups.

conclusionsOur pooled analysis demonstrated that distal unlocking of stable intertrochanteric fractures can shorten the operation time, reduce intraoperative bleeding, and reduce the blood transfusion rate. The use of locked or unlocked intramedullary nailing does not affect long-term outcomes regarding complications and function.
