Adjacent segment motion following multi-level ACDF: a kinematic and clinical study in patients with zero-profile anchored spacer or plate.
Article in European spine journal : official publication of the European Spine Society, the European Spinal Deformity Society, and the European Section of the Cervical Spine Research Society, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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 investigate the adjacent segment kinematics, including the instantaneous axis of rotation (IAR) and range of motion (ROM), after anterior cervical discectomy and fusion (ACDF), and to compare between ACDF with zero-profile anchored spacer (ACDF-Z) and ACDF with plate (ACDF-P).
methodsEighty-seven patients (ACDF-Z = 63; ACDF-P = 24) were included. Flexion, extension and neutral cervical radiographs were obtained before operation and at 1-year follow-up. C2-C7 ROM, adjacent segment ROMs, and IARs were measured. Clinical evaluation was based on the Visual Analogue Scale, Neck Disability Index, and Japanese Orthopaedic Association score.
resultsAfter ACDF-Z, location of the superior IAR-AP reduced 1.60 mm, which represents 8% of the vertebral body (P < 0.001), and location of the inferior IAR-SI reduced 2.19 mm, 17% of the vertebral body (P = 0.02). After ACDF-P, location of the superior IAR-AP increased 0.8 mm, which means 6% of the vertebral body (P = 0.008), location of the inferior IAR-AP increased 3.34 mm, 22% of the vertebral body (P = 0.03), and location of the inferior IAR-SI reduced 3.14 mm, 25% of the vertebral body (P = 0.002). C2-C7 ROM significantly decreased after both ACDF-Z and ACDF-P (P < 0.001). Neither ACDF-Z nor ACDF-P significantly affected the adjacent segment ROMs (P > 0.05).
conclusionsBoth ACDF-Z and ACDF-P significantly impacted cervical kinematics, although both procedures obtained satisfactory clinical results in the treatment of cervical spondylosis. After both ACDF-Z and ACDF-P, C2-C7 ROM decreased significantly, while adjacent segment ROMs were preserved. ACDF-Z and ACDF-P impact the location of adjacent segment IAR-SI in similar way, while impact the location of adjacent segment IAR-AP in diverse ways.
