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
Background: Spinal manipulation is widely used in clinical practice, yet how contact site selection influences mechanical transmission through spinal structures remains poorly understood. This exploratory study characterizes the biomechanical transmission of impulsive spinal manipulative thrust (SMT) forces through the Methods: Four patients undergoing elective lumbar surgery were instrumented with triaxial accelerometers on intraosseous Steinmann pins at L2 and L4, and bilateral needle electromyographic (nEMG) electrodes. An Impulse iQ adjusting instrument delivered impulsive SMTs to six contact points in randomized order: L3 spinous process, L5 spinous process, and bilateral L2 and L4 facet joints totaling 1,549 usable for force-dependent analyses after excluding one patient with an instrument force malfunction. Patient-level aggregation (n = 3-4) served as the primary statistical approach. Results: Two patterns of mechanical transmission were observed. Spinous process contacts produced larger posterior-anterior vertebral acceleration at L2 in all patients (14.95 ± 10.97 vs. 6.75 ± 4.62 g, patient-level Conclusion: These exploratory findings suggest that contact site selection influences the transmission pathway architecture and directional character of the vertebral mechanical response during impulsive SMTs. These biomechanical observations may help generate hypotheses for future clinical studies examining the relationship between contact site selection and therapeutic outcomes.
