Exploring the efficacy and safety of Yu-Ping-Feng powder with variation against allergic rhinitis: a randomized, double-blind, placebo-controlled trial.
Article in Chinese medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
backgroundAllergic rhinitis (AR) is a common allergic condition characterized by frequent sneezing, nasal congestion, nasal itching and rhinorrhea. Chinese medicine formula Yu-Ping-Feng Powder with Variation (YPV) is an empirical formula modified from an ancient Chinese medicine formula named Yu-Ping-Feng Powder, which is widely used for the treatment of allergic diseases such as AR and asthma. PURPOSE: To evaluate the efficacy and safety of YPV on AR patients with the lung and spleen Qi deficiency type using a randomized, double-blind, placebo-controlled clinical trial (RCT). STUDY DESIGN AND
methodsBetween April 2022 and June 2023, a total of 58 participants were recruited and randomly allocated to receive either YPV (n = 29) or placebo (n = 29) for 8 consecutive weeks. The changes of the Total Nasal Symptom Score (TNSS), and the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) or the Paediatric Allergic Disease Quality of Life Questionnaire (PADQLQ) scores at week 8 were used as the primary outcomes. The secondary outcomes included (1) the change of TNSS at weeks 4, 12 and 16; (2) the RQLQ or the PADQLQ scores at weeks 4, 12 and 16; (3) the change of frequency of AR episodes and their severity Visual Analog Scale (VAS) at weeks 4, 8, 12 and 16; (4) the changes of the gut microbiota composition in stool samples at week 8; and (5) adverse events related to the study treatment.
resultsYPV treatment could significantly improve the RQLQ score in AR patients at weeks 4, 8, 12, and 16 (p = 0.05, p = 0.04, p = 0.04 and p = 0.03, respectively), when compared with the placebo treatment. However, it did not improve the TNSS score at week 8 in AR patients when compared with the placebo group. In addition, YPV treatment could reduce the VAS score in AR patients at weeks 12 and 16 when compared with the placebo group, although the reductions were not statistically significant (p = 0.06 and p = 0.08, respectively). Importantly, no overt adverse effects were observed in both YPV and placebo groups.
conclusionYPV was well-tolerated and could effectively ameliorate multiple symptoms of AR and improve the quality of life of AR patients after 8-week treatment.
