Circumferential dynamic stabilization of the lumbar spine: a biomechanical analysis.
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, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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 assess segmental angulation and mobility following implantation of the Charité artificial disc in combination with the posterior dynamic fixation device dynamic stabilization system (DSS) and the interspinous spacer Coflex at the L4-L5 segment, respectively.
methodsSix human L4-L5 specimens were loaded with pure moments of ±7.5 Nm in flexion/extension, lateral bending, and axial rotation in a custom-made spine tester. The testing protocol was as follows: (a) intact condition, (b) destabilization by resection of the anterior longitudinal ligament (ALL), (c) implantation of the Charité with retained posterior longitudinal ligament (PLL), (d) supplemental DSS implantation, (e) removal of DSS rods and PLL resection, (f) DSS rod re-implantation, (g) enlargement of rod length, and (h) removal of DSS and implantation of Coflex. Range of motion (ROM), neutral zone, and segmental angulation were determined.
resultsALL resection did not influence significantly ROM. TDR increased lateral bending and axial rotation only after resection of the PLL, whereas flexion/extension remained unchanged. DSS limited all degrees of freedom prior to and after PLL resection. Rod length enlargement had no significant effect. Coflex limited significantly flexion/extension compared to the intact state and TDR, whereas lateral bending and axial rotation remained unchanged. TDR increased lordosis, whereas Coflex had a substantial kyphosing effect.
conclusionsThis study demonstrates that posterior dynamic stabilization in combination with TDR reduces flexion/extension ROM and segmental lordosis in a monosegmental biomechanical model.
