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

backgroundThe Parkinson's Disease Questionnaire (PDQ-39) is a well-validated British scale for the assessment of health-related quality of life (QoL) in Parkinson's disease (PD).

objectiveTo validate the Serbian version of the PDQ-39, while also providing additional information on the characteristics of this instrument. PATIENT AND

methodsA total of 102 Serbian PD patients were asked to complete the PDQ-39, a disease-specific QoL questionnaire, as well as the generic, health status questionnaire (SF-36-version 1), and the 21-item Beck Depression Inventory. Neurological examination included the Hoehn and Yahr staging, Unified Parkinson's disease rating scale (UPDRS)-part III, Schwab and England scale, and the Mini-Mental State Examination.

resultsInternal consistency analysis yielded a Cronbach's alpha of 0.83. Cronbach's alpha was above 0.70 for seven out of eight subscales (range from 0.73 to 0.91). A hierarchical structure of the PDQ-39 was revealed, with one global higher-order factor and two lower-order factors. The strongest predictor of the QoL in PD was the presence of depression, while motor disability (UPDRS-part III score) additionally contributed to poor QoL. Cognitive impairment has not been correlated with poor QoL. Also, QoL measures were not different between young- (< or =50 years) and older-onset PD patients.

conclusionsThe PDQ-39 is a reliable and valid instrument for the assessment of QoL in Serbian PD patients.
