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

This in-vitro study sought to characterize a concept for humeral component positioning during Total Elbow Arthroplasty (TEA) with bone defects. One-hundred specimens were analysed focusing a potential side-specific consensus; anatomical and Computed Tomography (CT) agreements; age-, sex- and humeral length-dependent associations. The angle of rotational alignment was defined by measuring the relationship between the flexion-extension axis (FEA) of the elbow joint and the flat posterior surface of the distal humerus (PDH). Three independent observers determined the reliabilities. The intraclass correlation coefficients (ICC), Pearson correlation coefficients (r), t-tests (r, p), and levels of 95% confidence interval were computed. P-values (p) were set with 0.05. An average internal rotation angle of the FEA to the PDH from 13.0° (range 6.4-27.1) was specified. Anatomical and CT measurements exposed strong agreements (r = .923, p < .001) and excellent observer agreements (ICCs > 0.900). A contralateral side consensus (r = .906, p < .001) and a statistically significant sex difference (at mean: female: 15.1° versus male: 11.5°; p < .001) was verified. No age- and humeral length-dependent correlations were observed (r < .300). Knowledge of these anatomical landmarks and their spatial relationships can provide an essential reference for surgeons striving to replicate native joint alignment. Additionally, assessment of the contralateral (uninjured) side via CT imaging may offer a valuable template and should be considered in the management of complex TEA cases.
