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: The complications of mobile cement spacer are common. To address these issues, a novel on-bone femoral molding device (FMD) has been developed to enhance stability between the spacer-bone. This study investigated the clinical outcomes and complications associated with this novel FMD. Methods: The FMD was developed using a reverse engineering program with the on-bone molding concept. Five knees of 4 patients were examined. The bone status, ambulatory ability, knee range of motion, and femoral spacer complications were followed up until 3 months after the second-stage surgery. Results: The infection was successfully treated in all patients. The interim period was 21.6 ± 4.5 weeks. The range of motion measured before the first surgery, before the second surgery, and 3 months after the second surgery was 104.2 ± 43.1, 105.8 ± 20.0, and 124.0 ± 18.5 degrees, respectively. No femoral spacer complications were observed. One knee joint subluxation and 1 minor tibial spacer fracture occurred. Conclusions: Newly developed FMD appears safe during initial proof-of-concept in patients with stage 1 to 2B bone loss. It prevents femoral spacer complications in a specific bone defect type without causing additional bone loss and facilitates range of motion during the interim period. Precise gap assessment and appropriate tibial cement spacer thickness could prevent knee dislocation.
