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
To investigate the contamination status of foodborne viruses in fresh fruits, vegetables, and their ready-to-eat (RTE) products sold in Shijiazhuang, China, a total of 365 samples were collected from farmers' markets, fresh produce stores, and large supermarkets between 2024 and 2025. Samples were tested for Norovirus (NoV) GI, NoV GII, Hepatitis A virus (HAV), Paslahepevirus balayani (HEV), Classic Human astrovirus (HAstV), and Sapovirus (SaV) using quantitative multiplex real-time reverse transcriptase-polymerase chain reaction (MRT-qPCR). Overall, foodborne viruses were detected in 93 samples (25.48%, 93/365). Detection rates of NoV GI, NoV GII, HAV, HEV, HAstV, and SaV were 11.78% (43/365), 9.04% (33/365), 0.27% (1/365), 4.93% (18/365), 0.27% (1/365), and 2.19% (8/365), respectively, with Norovirus being the dominant contaminant. The mixed contamination rate was 2.47% (9/365), mainly involving dual-virus contamination. Contamination was highest in coriander (32.50%, 13/40), followed by cherry tomatoes (31.82%, 21/66) and blueberries (30.77%, 20/65). The detection rate of foodborne viruses in fresh produce (26.89%, 89/331) was higher than that in RTE products (11.76%, 4/34) (χ
