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
backgroundAnxiety disorder is one of the most common and disabling neuropsychiatric syndromes in patients with Parkinson's disease (PD), seriously affecting the quality of life and prognosis of PD patients.
objectiveThe objective of this study was to analyze the risk factors for anxiety in PD patients and to evaluate the effectiveness of cognitive behavioral therapy (CBT) in treating PD with anxiety disorder (PDAD).
methodsBaseline data were recorded for 211 PD patients and 139 PDAD patients, and multi-factorial and independent risk factors for anxiety disorder in PD patients were analyzed. The 139 PDAD patients were divided into clinical testing (CMO) and CBT groups. Assessments were taken at baseline and after the end of the intervention. A 5-month follow-up survey was conducted after the intervention. The mouse PD model was induced by MPTP, and the anxiety state of mice was detected by rotarod test and open-field test. The expression of BDNF/PI3K/Akt protein in serum and mouse brain was detected by western blot.
resultsPDAD patients had significantly higher HAMA scores than PD patients. PSQI, ESS, HAMD, SCOPA-AUT, UPDRS-III and Hoehn-Yahr were independent risk factors for anxiety disorder in PD patients. After the intervention, the psychological state, cognitive function and quality of life improved in both the CMO and CBT groups, with the CBT group showing better improvement Results from follow-up showed that the number and frequency of falls was lower in the CBT group than in the CMO group, and that patients were more satisfied with the CBT intervention than the CMO group. L-dopa treatment alleviated anxiety in PD mice. L-dopa treatment increased BDNF, p-PI3K, and p-Akt protein levels. Moreover, the combination of L-dopa and CBT enhanced the boosting effect of L-dopa on these proteins.
conclusionCBT is an effective treatment for anxiety in patients with Parkinson's disease. Medications combined with CBT have been shown to be effective in improving depression, anxiety and quality of life in PDAD patients.
