1 · What the graph read from 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.

2 · The registry

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

backgroundAxial postural abnormalities (APAs) are common, disabling complications of Parkinson's disease (PD) with unclear pathophysiology. The presence of hyperactivity in multiple trunk muscles supports the use of botulinum toxin (BTA). However, its application is complex, due to the lack of standardized clinical and electrophysiological approach.

objectivesTo evaluate BTA injections effectiveness using a clinical algorithm that integrates trunk angle severity and electromyography (EMG)-detected muscle hyperactivity in patients with APAs.

methodsThis is prospective, open-label, pilot study. A novel decisional algorithm guided muscle selection, based on the bending degree and EMG findings. PD patients with different APAs underwent trunk angle measurement and EMG polygraphy of axial muscles in the standing position and during trunk activation. Primary outcome was the change in trunk misalignment measured before and one month after BTA injection. Secondary outcomes were the Clinical Global Impression of Change-Improvement (CGI-pain and CGI-posture) and the Numeric Rating Scale (NRS) for pain.

resultsAmong 52 PD patients, 20(38.5%) were eligible for treatment. At one-month follow-up, lateral trunk flexion (LTF) improved [LTF angle from 11.5 (CI 7.1-15.9) to 9.9, (CI 5.2-14.7) P = 0.013], while anterior trunk flexion (ATF) did not (thoracic fulcrum ATF from 41.4 to 40.6, P > 0.05; lumbar fulcrum ATF from 25.7 to 24.5, P > 0.05). CGI-posture improved in 45% of cases, CGI-pain improved in 50% of cases, and NRS decreased from 6.3 to 4.8 (P = 0.010).

conclusionsA clinical and neurophysiological algorithm integrating measures of trunk bending and EMG-detected muscle hyperactivity can optimize BTA treatment for APAs in PD, improving motor/ non-motor outcomes.
