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
backgroundMedial branch blocks (MBB) and radiofrequency ablations (RFA) are common diagnostic, prognostic, and interventional procedures performed for the management of cervical and lumbar spine facetogenic pain. Although these procedures have established utility as pain management strategies, it is unclear if the disruption in function of the medial branch nerve leads to patient balance impairment.
objective(1) To determine if there was a difference in postural balance, measured using a head mountable physiological vibration acceleration (Phybrata) sensor, between those pursuing cervical or lumbar MBBs/RFAs compared to an asymptomatic healthy cohort (HC). (2) To determine differences in balance and sensory reweighting prior to and following MBBs/RFAs, and the association with clinical measures of pain and balance using the 4-Stage Balance Test.

participantsSixty individuals with chronic axial back pain and 60 age-/gender-matched healthy individuals. INTERVENTIONS/
main outcome measuresStanding balance measures recorded with the Phybrata sensor, subjective report of pain (numerical rating scale), and clinical measures of balance (4-Stage Balance Test) were analyzed before and after participants underwent MBBs/RFAs and compared to an asymptomatic HC.
resultsParticipants with axial spinal pain of facet joint origin (≥ 50% relief post MBB/RFA) demonstrated balance degradation when standing with eyes closed, when compared to participants with nonspecific axial spinal pain (< 50% pain relief) or HCs - both prior to and following MBBs/RFAs. Following MBBs/RFAs, participants undergoing C2/3 procedures demonstrated increased postural sway. The remainder of participants with axial spinal pain did not show any further balance deficits, with corresponding sensory reweighting adaptation. Phybrata measures were not associated with pain location or pain intensity prior to or after MBBs/RFAs.
conclusionsThese results suggest the risk of developing significant balance impairments following MBB/RFA procedure of either the cervical (excluding C2/3) or lumbar spine is low, although residual balance deficits remain.
