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
backgroundIntracardiac echocardiography (ICE) is increasingly used to guide cardiovascular interventions. This study compared the performance of ICE with transesophageal echocardiography (TEE) in device closures of interatrial communications.
methodsA systematic search through PubMed, Scopus, Cochrane Library, and Europe PMC identified clinical studies directly comparing ICE and TEE as imaging guidance modalities for percutaneous closure of ASD or PFO in pediatric and adult populations. The key outcomes encompassed procedural time, fluoroscopy time, procedural success, complete closure at the latest follow-up, and major and minor complications. Pooled mean differences (MD) and risk ratios (RR) with corresponding 95% confidence intervals (CI) were measured by applying the random-effects model.
resultsTwelve studies comprising 5054 participants (ICE = 2480; TEE = 2574) were included in the quantitative analysis. Meta-analysis demonstrated a numerically shorter procedural time (MD -20.80 min; 95% CI -29.84 to -11.75; p < 0.00001), but not fluoroscopy time (MD -1.17 min; 95% CI -2.64 to 0.30; p = 0.12), in the ICE group compared with the TEE group. Procedural success rates and complete closure at the latest follow-up were comparable between both imaging strategies. In safety analyses, ICE was associated with a meaningful reduction of risk of major complications compared to TEE (RR 0.77; 95% CI 0.64 to 0.92; p = 0.004). Comparable findings were observed in the incidence of minor complications.
conclusionICE represents a promising alternative imaging modality for guiding transcatheter closure of ASD and PFO. Compared with TEE, ICE is associated with a numerically reduced procedural duration and a lower incidence of major complications, while maintaining comparable procedural success and long-term closure rates.
