Accuracy of computer-assisted drilling of equine cervical vertebral bodies using a purpose-built cervical frame-An experimental cadaveric study.

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
objectiveTo assess the accuracy of computer-assisted surgery (CAS) of equine cervical vertebrae using a purpose-built cervical frame (CF) for neck stabilization. STUDY
designExperimental cadaveric study. SAMPLE POPULATION: Six whole fresh equine cadavers.
methodsCadavers were positioned in dorsal recumbency with the neck extended within the CF. A cone-beam computed tomography (CBCT)-based surgical navigation system with optical tracking was used. A ventral approach exposed cervical vertebrae C3-C5. In each cadaver, 12 drill corridors were prepared with the patient tracker on the CF (position CF), followed by 12 corridors with the patient tracker on C3 (position C3). Surgical accuracy aberration (SAA) was assessed by measuring Euclidean distances between planned and executed entry and target points on merged pre- and postoperative datasets. Descriptive statistics and repeated-measures analyses of variance (rep.-meas. ANOVA) compared SAA measurements between groups.
resultsThe mean ± SD SAA (Euclidean distance) was 2.00 ± 0.98 mm in patient tracker position CF, and 2.41 ± 1.31 mm in position C3 (rep.-meas. ANOVA p = .215). At the most dorsal point of the drill corridor, dorsoventral deviations >2 mm occurred in 5/72 measurements in patient tracker position CF, and in 12/72 measurements in position C3.
conclusionThe CF allowed for unrestricted pre- and intraoperative CBCT imaging and computer-assisted drilling with a SAA in the close range of 2 mm. Positioning the patient tracker on the CF, outside the surgical field, did not compromise surgical accuracy. CLINICAL SIGNIFICANCE: A CF can facilitate CAS for surgeries with a ventral approach to the equine cervical vertebral column.
