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

Objective: To evaluate the agreement of cone-beam computed tomography arthrography (CBCTA) and magnetic resonance imaging (MRI) in detecting osteoarthritic changes of the knee. Design: This comparative study included 58 knee joints in 54 symptomatic subjects with suspicion of knee osteoarthritis (OA). The symptomatic joints were imaged using CBCTA and 3T MRI and graded using the MRI Osteoarthritis Knee Score (MOAKS). Agreement between modalities was assessed using prevalence and bias adjusted kappa (PABAK), percentages of exact (PEA) and close agreement (PCA) of ±1 in MOAKS grades and participant-specific comparisons. Results: CBCTA was performed with acceptable intra-articular concentration in 86.2 % ( Conclusions: CBCTA demonstrates moderate to almost perfect agreement with 3T MRI for knee OA findings. Although 13.8 % of the arthrographies had failed in our study, CBCTA offers a practical alternative when MRI is contraindicated or unavailable.
