Introduction and An Analysis of Inter- and Intra-observer Validity to the Classification of Hoffa-Like Tibial Plateau Fractures.

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.
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 posterior coronal shearing fractures of the tibial plateau are rare and can be easily missed or ignored. Our team defined these fractures as Hoffa-like fracture of the tibial plateau and conducted a series of studies. The aim of this study is to introduce the characteristics of the Hoffa-like fracture of the tibial plateau, propose a new classification system and evaluate its validity.
methodsSixty-one patients with Hoffa-like fractures of the tibial plateau were treated in five trauma centers (I-III) from 2017 to 2020. A new classification system was developed based on the morphological fracture patterns in CT and radiographic of the first 30 cases. Ten cases of suspected tibial plateau Hoffa-like fractures were supplemented additionally to the 61 cases to increase the accuracy. CT and radiographic images of the 71 cases were reviewed independently by four reviewers on two separate occasions and classified according to the new classification system. Cohen's kappa coefficient (κ) was used to analyze the reliability on separate observers at the same time and to analyze the classification made by same observer at different times (intra-observer), which measures inter-observer and intra-observer agreements.
resultsOut of the 61 patients, 46 (75.4%) isolated coronal fractures involving the medial condyle of tibial plateaus and 53 (86.9%) combined with intercondylar spine fractures. The κ-values were calculated for the new classification system (mean κ = 0.74 inter-observer, mean κ = 0.79 intra-observer, indicating substantial agreement).
conclusionThe novel classification lends insight into fracture morphology of the tibial plateau Hoffa-like fractures, has good inter- and intra-observer validity, and it aids in treatment.
