High-Resolution Anorectal Manometry and Balloon Expulsion Test Outcomes in Functional Constipation: A Comparative Study.
Article in Medical science monitor : international medical journal of experimental and clinical research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07705542 (Analysing the Impact of Balloon Inflated vs Balloon Deflated Push Manoeuvres in Chronically Constipated Patients During Biofeedback Therapy), which is not on this map. Not yet cited in PubMed.
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
BACKGROUND Functional constipation can occur in children and adults and consists of difficult or infrequent bowel movements, painful defecation, or the sensation of incomplete bowel movement, and it can be idiopathic. This study aimed to compare the findings from high-resolution anorectal manometry (HRAM) and the balloon expulsion test (BET) in 360 patients with functional constipation and 73 healthy volunteers. MATERIAL AND METHODS In total, 360 patients with functional constipation and 73 healthy volunteers underwent HRAM and BET in our hospital from January 2017 to December 2023. We collected the general data of all participants and surveyed the defecation symptoms of patients with functional constipation. RESULTS Our study showed no significant correlation between HRAM results and age in healthy volunteers, while men had a higher residual anal pressure (P=0.022), higher anal squeeze pressure (P=0.020), and lower rectoanal pressure gradient than women (P=0.017). Using logistic regression analysis, it was concluded that sex (OR=2.880, 95% CI [1.654,5.015], P=0.000) and sensation of incomplete evacuation (OR=1.892, 95% CI [1.023,3.500], P=0.042) affected the occurrence of dyssynergic defecation. The specificity of BET in diagnosing dyssynergic defecation was 81.89%, while that of HRAM was 52.78%. CONCLUSIONS This observation provides normal values for anorectal pressures by HRAM. HRAM and BET are effective methods for assessing functional constipation. Being male and having sensation of incomplete evacuation are risk factors for dyssynergic defecation. The specificity of BET for diagnosing dyssynergic defecation was higher than that of HRAM.
