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

purposeGeneric preference-based quality of life (PbQoL) measures are sometimes criticized for being insensitive or failing to capture important aspects of quality of life (QoL) in specific populations. The objective of this study was to systematically review and assess the construct validity and responsiveness of PbQoL measures in Parkinson's.

methodsTen databases were systematically searched up to July 2015. Studies were included if a PbQoL instrument along with a common Parkinson's clinical or QoL measure was used, and the utility values were reported. The PbQoL instruments were assessed for construct validity (discriminant and convergent validity) and responsiveness.

resultsTwenty-three of 2758 studies were included, of which the majority evidence was for EQ-5D. Overall good evidence of discriminant validity was demonstrated in the Health Utility Index (HUI)-3, EQ-5D-5L, EQ-5D-3L, 15D, HUI-2, and Disability and Distress Index (DDI). Nevertheless, HUI-2 and EQ-5D-3L were shown to be less sensitive among patients with mild Parkinson's. Moderate to strong correlations were shown between the PbQoL measures (EQ-5D-3L, EQ-5D-5L, 15D, DDI, and HUI-II) and Parkinson's-specific measures. Twelve studies provided evidence for the assessment of responsiveness of EQ-5D-3L and one study for 15D, among which six studies reached inconsistent results between EQ-5D-3L and the Parkinson's-specific measures in measuring the change overtime.

conclusionsThe construct validity of the PbQoL measures was generally good, but there are concerns regarding their responsiveness to change. In Parkinson's, the inclusion of a Parkinson's-specific QoL measure or a generic but broader scoped mental and well-being focused measure to incorporate aspects not included in the common PbQoL measures is recommended.
