Asymmetry of Subthalamic Neuronal Firing Rate and Oscillatory Characteristics in Parkinson's Disease.
Article in Neuropsychiatric disease and treatment, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 4 papers.
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
purposeThe aim of this study was to compare the neuronal firing rate and oscillatory activity of the subthalamic nucleus (STN) between the more affected (MA) and the less affected (LA) hemispheres in Parkinson's disease (PD). PATIENTS AND
methodsWe recorded and analyzed the intra-operative microelectrode recordings (MER) from the STN of 24 PD subjects. Lateralized Unified Parkinson's Disease Rating Scale (UPDRS) III sub-scores (item 20-26) were calculated. The STN corresponding to the MA side was designated as the MA STN while the other side as the LA STN. Single unit characteristics including interspike intervals were identified and spectral analyses were assessed. Further, the mean spontaneous firing rate (MSFR) of neurons was calculated. The correlations between clinical symptoms and neuronal activity were analyzed.
resultsThe firing rate in the MA and LA sides were 43.18 ± 0.74 Hz and 36.94 ± 1.32 Hz, respectively, with an increase of 16.9% in the MA group. The number of neurons that oscillated in the Tremor-Frequency Band (TFB), β-Frequency Band (βFB), and the non-oscillatory cells in the MA group were 43, 115, and 62 versus 78, 68, and 54 in the LA group, respectively. The proportions of the three types of neurons were different between both groups. The firing rate of the STN neurons and the UPDRS III sub-scores were positively correlated. Additionally, we observed a positive correlation between the percentage of βFB oscillatory neurons and bradykinesia score.
conclusionThe firing rate of the STN in the MA hemisphere is higher than in the LA side, following disease progression and there seems to be an increase in firing rate. The βFB oscillatory neurons are at a larger proportion in the MA group while there were larger percentage of TFB oscillatory cells in the LA group. The proportion of βFB oscillatory neurons is selectively correlated with the severity of bradykinesia.
