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
Background: Gastrointestinal discomfort in infants and toddlers is common, yet many cases may not meet the Rome IV diagnostic criteria, posing a challenge to clinical management. To address this gap, Chinese experts have proposed the novel diagnostic entity "functional dyspepsia syndrome in infants and toddlers" (FDSIT). Therapeutic options for functional gastrointestinal disorders in infants and toddlers remain considerably limited, particularly with regard to conventional Western pharmacotherapies. Wangshi Baochi Pill (WBP), a traditional Chinese medicine with a long history of pediatric use, has shown efficacy in older children (≥4 years) with functional dyspepsia. However, its efficacy and safety for FDSIT remain unclear. This study aimed to assess the efficacy and safety of WBP in infants and toddlers diagnosed with FDSIT according to the Chinese expert consensus. Methods: This multicenter, randomized, double-blind, placebo-controlled trial was conducted across 15 hospitals in China. Eligible participants aged 1-36 months were randomly assigned (1:1, block size 4) to receive WBP (2 mg/kg twice daily) or a matching placebo for 7 days, with follow-up through day 14. The primary endpoint was the combined symptom effectiveness rate (CSER) at day 7, defined as the proportion of participants achieving a ≥50% reduction in total symptom score across five prespecified symptom domains, each graded on a 4‑point scale. Secondary endpoints included CSER at days 3 and 14, individual symptom remission rates, growth parameters, and adverse events (AEs), which were systematically monitored via diary cards and clinical assessments. Results: There were 240 infants and toddlers randomized; 229 were included in the full analytical set (WBP, n=113; placebo, n=116). Baseline characteristics were well balanced. At day 7, CSER was significantly higher in the WBP group than in the placebo group [69.03% Conclusions: In this trial, WBP demonstrated notable efficacy and a favorable short-term safety profile for the treatment of FDSIT. These findings suggest that WBP may represent a potential therapeutic option, although further confirmatory studies are warranted.
