Efficacy and safety of non-pharmacological treatments for paediatric functional constipation: a systematic review and meta-analysis.
Synthesis in BMJ paediatrics open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
backgroundRecent studies have expanded the evidence on novel and existing non-pharmacological treatments for paediatric functional constipation (FC). This study aimed to systematically review the efficacy and safety of non-pharmacological therapies for FC in children.
methodsPubMed, MEDLINE, Embase, PsycINFO, Cochrane Library and trial registries were searched from inception to March 2025. Randomised controlled trials (RCTs), including children (0-18 years) with FC treated with non-pharmacological interventions compared with placebo, no treatment or other interventions, were included. Primary outcomes were treatment success, defecation frequency and withdrawals due to adverse events. Dual data extraction and appraisal was conducted. Certainty was assessed using Grading of Recommendations, Assessment, Development and Evaluations (GRADE).
results93 RCTs comprising 7787 children (50.4% female) were included investigating dietary, psycho-educational, physiotherapeutic interventions, various complementary and complementary medicine interventions, and electrical stimulation. A substantial part of the therapies provided evidence that was of very low certainty, meaning no conclusions could be drawn. Abdominal transcutaneous electrical stimulation plus pelvic floor muscle exercises (PFME) may improve treatment success and defecation frequency compared with PFME alone (risk ratio (RR): 1.75 (95%CI 1.25 to 2.44) and mean differences (MD): 1.85 (95%CI 1.28 to 2.43), moderate certainty). Percutaneous tibial nerve stimulation plus PFME leads to more treatment success (RR: 1.73 (95%CI 1.08 to 2.77), low certainty) and greater defecation frequency (MD: 1.82 (95%CI 0.82 to 2.82), moderate certainty). Behavioural therapy plus polyethylene glycol may not improve treatment success (RR: 0.83 (95%CI 0.62 to 1.12), low certainty) and probably reduces defecation frequency (MD: -1.80 (95%CI -2.88 to -0.72), moderate certainty).
conclusionsImprecise data, poor reporting and substantial heterogeneity led to downgrading in GRADE assessments. Some non-pharmacological treatment options for children with FC show beneficial effects, and these may be considered in the management of children. Future trials should aim to improve methodological rigour. PROSPERO REGISTRATION NUMBER: CRD42023416891.
