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

objectiveTo assess the effects of an Iyengar yoga program (IYP) on patients with chronic respiratory diseases.

methodsPatients attending lung transplant clinics in a tertiary institution were invited to participate in a two-phase, 12-week IYP that included 2 h biweekly classes. Doctors completed a formal physical and clinical assessment on candidates before enrollment. Patients with New York Association Class III or IV, or dyspnea grade IV were excluded. At baseline and at the end of 12-weeks, patients completed the Hospital Anxiety and Depression Scale (HADS), Chronic Respiratory Questionnaire (CRQ) and Health Utilities Index (HUI). Medication(s), 6 min walk test results and other clinical parameters were also recorded. Patients recorded the effects of the IYP on their daily living in journals. Nonparametric and qualitative methods were used to analyze the data.

resultsTwenty-five patients diagnosed with pulmonary arterial hypertension and chronic obstructive pulmonary disease (mean age 60 years) were invited to participate. At the end of the 12-week period, changes in HADS anxiety and CRQ fatigue scores were statistically significant (P<0.05) and changes in HUI ambulation, pain, emotion and overall score were clinically important. The content of the journals revealed patients' improvement in breathing capacity, mobility, energy, sleep and included positive feedback such as: "increased tidal volume with slowing expiration", "I have an overall feeling of wellbeing" and "excellent amount of energy".

conclusionsThe findings suggest that yoga has significant potential to produce benefits. Potential benefits will be further explored in a national multisite study.
