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

purposeIn shoulder arthroplasty, three-dimensional computed tomography (3D CT) has become the gold standard for preoperative version assessment. Meanwhile, postoperative version is usually evaluated using radiographs (XR), in particular an axillary view, in which the view of the scapular body is often truncated, preventing the scapular plane from being used as a reference. This study introduces the posterolateral acromion-to-coracoid (PLAC) line, which can be assessed on a standard truncated axillary radiograph. MATERIALS AND

methodsForty-six shoulders were studied. Four angles were measured including 3D CT (CT Version), 3D CT PLAC line to glenoid face angle (CT PLAC-GFA), 2) radiographic PLAC line to glenoid face angle (XR PLAC-GFA), and 3) the radiographic glenoid vault line to glenoid face angle (XR GV-GFA). Variation and linear relationship between these angles were calculated.

resultsThe mean difference between CT PLAC-GFA and XR PLAC-GFA was 1.0º (95% CI -0.7 to 2.8)(IQR = 8.5º, -3.0º to 5.4º), with a strong correlation on linear regression (R

conclusionsThe PLAC and the glenoid vault lines are highly reproducible references on truncated axillary views. These alternative reference lines allow accurate comparison of preoperative and postoperative glenoid orientation using standard axillary radiographs.
