The odontoid process: various configuration types in MR examinations.
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 10 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
purposeSeveral developmental anomalies have been described with respect to the odontoid process. The purpose of the study was to describe the MR appearance of the odontoid process and to calculate the prevalence of its morphological variants. METHODS AND MATERIALS: We retrospectively reviewed 133 patients (85 males and 48 females, age range of 19-81 years, mean 39.5), examined within a 7-year period. Patients were divided into two age groups: ≤30 and >30-year-old. The morphology of the odontoid process was classified into type I: pyramidal tip and type II: ovoid or convex tip. The incidence of os odontoideum and os terminale and the presence of longitudinal cleft were also recorded. Fischer's exact test was used for statistical analysis (p < 0.05).
resultsType I was identified in 54 cases (40.6 %) and type II in 79 cases (59.4 %). Os odontoideum was recorded in one case (0.7 %), os terminale in 24 cases (18 %) and the presence of a longitudinal cleft (partial or complete) in 86 cases (64.7 %). Type I showed a higher prevalence in the ≤30 age group (p < 0.05). No differences were shown between sexes.
conclusionThe configuration types of odontoid process are reported herein. The clinical relevance of this morphological variation needs to be elucidated with further studies.
