Evaluation of a Self-Management Program for Gastroesophageal Reflux Disease in China.

Patients were allocated by recruitment period rather than random assignment, so differences between the two time periods could have influenced results. The sample was small and follow-up was only 3 months, as the authors state. The intervention was a bundle of conventional drug therapy, education, diaphragm biofeedback, and massage, so the effect of any one component cannot be identified. Both groups received conventional drug therapy and lifestyle or diet instructions, so extra contact, monitoring, and education may explain part of the benefit. The paper reports many outcomes and does not name a single primary endpoint, making selective reporting harder to rule out. Self-management behavior was measured with a self-designed questionnaire, although pilot reliability and validity were reported. The prose does not state total group sizes, although Table 1 gives counts by category.

Do not conclude that diaphragm breathing or acupoint massage alone improved reflux symptoms. The experimental group also received conventional drug therapy and structured self-management education, and allocation was by recruitment period rather than random assignment. The paper does not isolate the contribution of any single component.
