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

objectiveThe aim of this meta-analysis was to explore the difference between and compare intramedullary fixation (IF) and extramedullary fixation (EF) for unstable intertrochanteric fractures.

methodsWe searched Pubmed database and Cochrane library following by including and excluding articles based from inception to December, 2016. All randomized controlled trials (RCTs) comparing IF and EF for unstable intertrochanteric fractures were assessed and selected by two researchers independently. Data were analyzed using Review Manager 5.1 version.

results17 RCTs were enrolled in our meta-analysis comparing IF and EF and showed evidence that IF had lower rate of implant failure RR = 0.2695%CI 0.13-0.51, P < 0.0001 and re-operation (RR = 0.60, 95%CI 0.37-0.98, P = 0.04), while there was no statistical differences of cut-out, postoperative infections and other complications. Moreover, PPM scores verified that IF had better postoperative hip mobility recovery (MD = 0.87, 95%CI 0.08-1.66, P = 0.03).

conclusionIF has lower incidence of failure of implant and reoperation and shows better postoperative functional recovery when treating adult unstable intertrochanteric fracture while the most postoperative complications were not statistically different from EF. LEVEL OF EVIDENCE: Level I, therapeutic study.
