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
backgroundHuman norovirus is a major cause of acute gastroenteritis across all age groups. This study investigated the prevalence, genotypes, and viral loads of noroviruses in adult patients with acute gastroenteritis.
methodsA hospital-based cross-sectional study was conducted between December 2021 and March 2023 in Thailand. The presence of noroviruses GI and GII in stool samples from patients with acute gastroenteritis were tested using RT-nested PCR and DNA sequencing. All norovirus GII-positive samples were further characterized by polymerase-capsid typing assay and semi-nested RT-PCR. Norovirus GII concentrations were determined by RT-qPCR.
resultsNorovirus GII was detected in 11.2% (28/250) of stool samples. Genotyping of the VP1 and RdRp genes identified GII.4 Sydney 2012[P31], GII.17[P17], and GII.17[P16], with GII.17[P16] being the most frequently detected. Of 28 norovirus GII-positive samples, the most common genotype was GII.17 (35.7%), followed by GII.17[P16] (32.1%), GII.17[P17] (14.3%), GII.4 Den Haag (7.1%), and GII.4 Sydney 2012[P31], GII.3 and GII.2 (3.6% each). GII.4 Sydney[P31] infections had the highest viral load (8.3 × 109 genome copies/g), followed by GII.17[P17] (8.9 × 105 - 4.5 × 108 genome copies/g) and GII.17[P16] (3.7 × 104 - 1.6 × 107 genome copies/g). GII.3 (2.4 × 104 genome copies/g), GII.4 Den Haag (1.7 × 10⁴ and 3.8 × 10⁴ genome copies/g) and GII.17 (2.4 × 10³-7.4 × 10⁴ genome copies/g) exhibited lower viral concentrations.
conclusionsThese findings provide important epidemiological insights into norovirus circulation, highlighting the emergence of GII.17[P16] and informing future outbreak preparedness and vaccine development.
