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
purposeSome cases of isolated unstable Jefferson's fracture of the Atlas verbebra require surgical fixation. Historical constructs with occipitocervical fixation or C1C2 posterior Harms-Goel fixation remain associated with functional impairment owing to limited postoperative cervical range of motion. Since 2004, motion-preserving C1 ring lateral mass screws with transverse rod (C1 LMF) has emerged as a possible technical alternative.
methodsRetrospective multicentric study of patients operated on for isolated unstable Jefferson's fracture of the Atlas vertebra using C1 LMF in two tertiary referral hospitals from South France.
resultsSince 2022, 9 patients (mean age 52.2 ± 20.5, male/female 7/2) were operated on by 5 different senior spine surgeon for Jefferson type 3 (6 cases) or type 4 (3 cases), with 8 cases of transverse ligament injury. Seven patients were treated in the acute setting (mean 2.9 ± 1.2 days), two patients were treated for chronic pseudarthrosis (mean 157.5 ± 116.7 days). Mean operative time was 108.7 ± 45.3 min with intraoperative blood loss of 233.3 ± 106.1, guided either by fluoroscopy (6 cases) or spinal navigation (3 cases). One patient had both screws misplaced medially without clinical consequence, requiring revision surgery. After a mean follow-up of 15.7 ± 7.8, self-assessed clinical outcome was excellent (VAS 1.3 ± 1.2, NDI 17.6 ± 8.9) with good cervical motion (rotation 57.8 ± 12.5°) and 66.7% of return-to-work. Bone fusion was achieved in 77.8%, with lateral mass distance reduction from 11.1 ± 3.6 mm down to 6.8 ± 3.3 mm.
conclusionThis small patient series suggests the long-term efficacy as well as the operative safety of C1 LMF for isolated unstable Jefferson's fracture.
