1 · What the graph read from 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.

2 · The registry

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

objectivesMonitoring for Helicobacter pylori (H. pylori)-eradication is important, since symptom improvement does not indicate treatment success. Using EuroPedHp Registry data, we investigated characteristics of children missing monitoring visits after prescribed therapy, compliance effect on eradication, and factors associated with loss to follow-up and low compliance.

methodsBetween 2017 and 2020, 30 paediatric hospitals from 17 European countries reported 1605 children with biopsy-proven H. pylori-infection. Children with prescribed therapy were analysed. Risk factors for loss to follow-up or low compliance (taking ≤90% of prescribed medications) were identified applying multivariable logistic regression.

resultsOf 1263 infected children with prescribed therapy, 390 (31%) were lost to follow-up. Risk factors for loss to follow-up included nausea/dyspepsia (p = 0.004) or gastrointestinal bleeding (p = 0.03) as indication for endoscopy, living in Israel or Türkiye (p = 0.0002), and having no antibiotic susceptibility result (p = 0.004). Risk decreased with living in Southern Europe (p = 0.002), migration background (p = 0.052), and probiotic use during therapy (p = 0.02). Low compliance, reported in 69/831 (8%) children with follow-up data, was associated with vomiting (p = 0.003), peptic ulcers or erosions (p = 0.03), living in EasternEurope (p = 0.009), Israel or Türkiye (p = 0.0008), and any adverse event during therapy (p = 0.0009). First-line tailored triple therapy (TTT) for 14 days (N = 480) was successful in 92% with excellent versus 61% with low compliance (p < 0.0001). After ≥1 failed therapies (N = 60), TTT was successful in 71% with high versus 13% with low compliance (p = 0.003).

conclusionThe registry data identified several factors associated with non-adherence to medication and monitoring visits. Improving information to patient/caregiver may increase adherence, care and treatment success.
