The preliminary results of a new CT-guided periradicular cervical steroid injection technique: safety and feasibility of the lateral peri-isthmic approach in 28 patients.
Article in Skeletal radiology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundComputed tomography (CT)-guided cervical nerve injections are broadly being used in the treatment of cervical radiculopathy; however, catastrophic complications have been reported. Herein, we aimed to evaluate the efficacy, feasibility, and safety of a novel CT-guided cervical injection technique. MATERIALS AND
methodsWe prospectively performed cervical injections in 28 patients with cervical radiculopathies using a novel CT-guided cervical transforaminal injection technique; lateral peri-isthmic approach in which the tip of the needle advanced to the lateral cortex of the isthmus instead of the foraminal area. Patients' pain reduction rates were evaluated using visual analog scores (VAS) at pre-treatment, immediately after treatment, at 3 weeks and 6 months after the treatment. Intra-vascular contrast medium injections and distribution of the contrast material into the foraminal, epidural or extraforaminal area during the procedure were noted.
resultsPre-treatment pain scores were reduced by 4.2 ± 1.4 (p < 0.001), 3.9 ± 1.37 (p < 0.001) and 3.25 ± 1.53 (p < 0.001) immediately after the treatment, 3 weeks and 6 months after the treatment respectively. The number of patients with >50% pain relief as measured by VAS were 21 (75%) immediately after the procedure, 19 (67.8%) at 3 weeks and 17 (60%) at 6 months after the procedure. The injected contrast material was dispersed into the neural foramen in 9 cases (32.1%), the foraminal and epidural area in 14 cases (50%) and the extraforaminal area in 5 cases (17.9%).
conclusionThe CT-guided lateral peri-isthmic approach seems to be a secure and feasible method for cervical injections with satisfactory pain reduction.
