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

backgroundChronic obstructive pulmonary disease (COPD) impairs quality of life and leads to premature mortality. COPD sufferers experience progressive deterioration of lung function and decreased ability to undertake day-to-day activities. Ginseng has been used for thousands of years in Chinese medicine for respiratory symptoms. Several controlled clinical trials using ginseng for COPD have shown promising clinical effect, however these studies were generally small and with some potential bias, prompting the need for rigorously designed studies.

aimThe objective of this study is to evaluate the therapeutic value and safety profile of a standardised root extract of Panax ginseng C.A Meyer (ginseng) for symptomatic relief, with a focus on quality of life (QoL) improvements in individuals with moderate (Stage II) COPD FEV1/FVC < 0.7 and FEV₁ 50%-80% predicted.

methodsThis paper describes the design of a randomised, multi-centre, double-blind, placebo controlled, two-armed parallel clinical trial. Two trial sites in Melbourne Australia will proportionately randomise a total of 168 participants to receive either ginseng capsule (100 mg) or matching placebo twice daily for 24 weeks. The primary outcomes will be based on three validated QoL questionnaires, St Georges Respiratory Questionnaire (SGRQ), Short Form Health Survey (SF-36) and the COPD Assessment Test (CAT). Secondary outcomes are based on lung function testing, relief medication usage and exacerbation frequency and severity. Safety endpoints include blood tests and adverse event reporting. Intention-to-treat will be applied to all data analyses. DISCUSSION: Findings from this study may lead to new therapeutic development for chronic respiratory diseases, particularly COPD. This protocol may also guide other investigators to develop quality herbal medicine clinical trials in the future.
