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 and study aims: Comprehensive genome profiling (CGP) is gaining importance in management of biliary and pancreatic cancers; therefore, obtaining ideal tissue samples is critical. Although percutaneous biopsy has been the first-line method of sampling liver tumors, recent advances in endoscopic ultrasound (EUS)-guided tissue acquisition (EUS-TA), particularly introduction of fine-needle biopsy (FNB) needles capable of obtaining larger tissue samples, suggest that EUS-TA may be an alternative for obtaining ideal specimens for CGP. However, few studies have evaluated the utility of EUS-TA with CGP for liver tumors. This study aimed to assess the role of EUS-guided FNB (EUS-FNB) in collection of ideal liver tumor samples for CGP and analyses. Patients and methods: This retrospective study included 36 patients with liver tumors who underwent EUS-FNB. Histological diagnostic accuracy, rate of obtaining ideal samples for CGP, and impact of procedural factors, such as needle gauge, tumor size, and number of punctures, were analyzed. Results: EUS-TA achieved a histological diagnostic accuracy rate of 94.4%, and the rate of obtaining ideal samples for CGP was 63.9%. Subgroup analysis showed that 22G (70.4%) and 19G (100%) needles were significantly more effective than 25G needles (16.7%) for obtaining ideal samples for CGP ( Conclusions: EUS-FNB is highly effective for obtaining ideal samples for CGP and achieving an accurate histological diagnosis. The 22G and 19G needles were significantly superior to 25G needles, thus emphasizing their importance in precision medicine.
