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

purposeTo evaluate the trends and patterns of cervical degenerative disc disease in the cervical spine in different age groups of symptomatic patients.

methodsOverall, 1300 symptomatic patients who had undergone cervical spine MRI from February 2019 to November 2021 were included. Pfirrmann grading was used to evaluate the IVD degeneration. Patients were divided into five groups based on age: group 1 from 20 to 29 years, group 2 from 30 to 39 years, group 3 from 40 to 49 years, group 4 from 50 to 59 years, and group 5 from 60 years and above. The patterns, severity, and the number of degenerated levels in each age group were analysed.

resultsThe total number of degenerated IVDs (grades IV and V) increased significantly with age, ranging from 76 (4.9%) in group 1 to 677 (43.4%) in group 5. The most common degenerated levels were C2/3 (25% of the total degenerated levels) in group 1, C5/6 (29.0%) in group 2, C5/6 (33.1%) in group 3, C5/6 (31.3%) in group 4, C5/6 (24.8%), in group 5. The number of degenerated IVDs increased significantly with age (P < 0.001). In patients with two or more degenerated levels, contiguous-level disc degeneration was more common than skip lesions.

conclusionThis study evaluated the severity and pattern of cervical disc degeneration at each level in different age groups. The severity and number of degenerated levels increased significantly with increased age. Adjacent-level degeneration is more common than skip lesions in patients with more than one-level degeneration.
