Evidence Map

What The Sources Report

• NSAIDs have been found to be more effective than placebo in relieving pain in women with primary dysmenorrhea, but they increase the risk of adverse effects, such as mild neurological symptoms (headache, drowsiness, dizziness) and gastrointestinal symptoms (nausea, indigestion). [Ma Wenyi (2026); evidence level 3]
• However, when combined OCP is used, there is an additional deep vein thrombosis (DVT) in every 1,000 women, and a higher risk is observed in users aged 6-12 months before use and over 40 years old. [Ma Wenyi (2026); evidence level 3]
• Although IBS has not been associated with an increase in mortality, its symptoms, mainly diarrhea, constipation, and abdominal pain, are debilitating and may strongly impair patients' quality of life, affecting physical, emotional, and social functions and leading to reduced travel, sex avoidance, and time spent with friends and family. [Abalo Raquel (2025); evidence level 3]
• This review aims to illustrate recent advances in the herbal-based remedies for IBS, focusing on the evidence reporting their mechanisms of action, their efficacy in alleviating symptoms and inflammation, and their potential safety concerns. [Abalo Raquel (2025); evidence level 3]

Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation
