The intra- and interobserver reliability of five commonly used intertrochanteric femur fracture classification systems.
Article in Joint diseases and related surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
objectivesThis study aims to evaluate the effect of surgical experience on reliability for Boyd-Griffin, Evans/Jensen, Evans, Orthopaedic Trauma Association (main and subgroups), and Tronzo classification systems. PATIENTS AND
methodsBetween January 2013 and December 2014, radiological images of a total of 60 patients (13 males, 47 females; mean age: 78.9±21.9 years; range, 61 to 96 years) with the diagnosis of intertrochanteric femur fracture were analyzed. Radiographs were evaluated and classified by five residents and five orthopedics and traumatology surgeons according to the Evans, Boyd-Griffin, Evans/Jensen, OTA, and Tronzo classification systems. Intra- and interobserver reliability were calculated using the kappa statistics.
resultsThe worst intraobserver compatibility among the residents was the classification system with OTA subgroups (κ=0.516), while the classification system with the best intraobserver fit was found to be OTA main groups (κ=0.744). The worst agreement among surgeons was in the Evans classification system (κ=0.456). However, the best intraobserver agreement was in the OTA main groups (κ=0.741). The best interobserver agreement was observed regarding the OTA main groups (κ=0.699).
conclusionThe classification that has the best harmony both among residents and surgeons, and between residents and surgeons is the OTA main group classification.
