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

purposeGait analyses are becoming increasingly relevant in digital medicine. For implementation in clinical practice, knowledge on differences between gait patterns of separate bone fracture types is required. The aim of this study was to compare longitudinal changes in gait of patients with proximal tibial, tibial shaft, and malleolar fractures, as well as nonunion.

methodsPatients with a proximal tibial, tibial shaft, or malleolar fracture requiring surgery were prospectively enrolled in this longitudinal observational study. A healthy control group received one measurement. Optical motion capture was used to obtain spatiotemporal gait parameters and kinematics at 6 weeks, 3 months, and 6 months after surgery.

resultsIn total, 73 patients (51.1 ± 16.9 years) and 43 controls (50.5 ± 17.7 years) were included. Only in malleolar fractures, all gait parameters had returned to normal after 6 months. Differences between fracture types at 6 weeks were found in step height (P = 0.01), knee range of motion (ROM, P < 0.001), and its asymmetry (P < 0.001). At 6 months, knee ROM was still lower in proximal tibial than tibial shaft and malleolar fractures (P = 0.04; 0.047). Tibial shaft fractures with and without nonunion differed in stance time (P = 0.007; 0.02) and its asymmetry (P = 0.007; 0.009) after 6 weeks and 6 months, but not at 3 months.

conclusionsWhen monitoring fracture healing with motion capture, differences between fracture types and their timely appearance should be considered.

trial registrationThe study was prospectively registered in the German Clinical Trials Register DRKS00025108.
