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
backgroundHerbs and dietary supplement (HDS) use has become increasingly used among the Thai population due to greater health awareness and easier product access. However, research on adverse events from HDS and information needs relating to HDS among the Thai population is limited. This study aims to explore use, adverse experiences, self-assessed knowledge and perspectives on HDS among the general public in Thailand.
methodsA cross-sectional self-administered survey in the general public conducted in 6 public areas in a large city of northeastern Thailand, over 5-month period. It explored experiences relating to use and adverse effects of HDS. Knowledge and information needs relating to HDS were self-assessed by using a visual analog scale and closed questions. The perspectives on HDS were determined using the 5 point-Likert scales for degree of agreement. Participants were selected by purposive sampling.
resultsOf the 1,064 questionnaires distributed, 540 (51.0%) respondents reported using herbal and dietary supplements (HDS). Among them, 363 (67.2%) used herbs, and 423 (78.3%) used dietary supplements, with 40.3% using these products infrequently in the past six months. Common herbs included andrographis (25.3%), turmeric (21.2%), and senna (6.9%), while vitamin C (41.8%), collagen (11.8%), and vitamin B complex (9.0%) were the most frequently used dietary supplements. Adverse effects were reported by 42 respondents, primarily associated with turmeric (25.0%) and vitamin C (31.8%), with most rating the severity as mild (76.2%). Self-assessed knowledge about HDS use and adverse effects was moderate, with a significant demand for information on interactions with medications (59.3%), adverse effects (57.0%), and actions to take if adverse effects occur (52.8%). Higher education levels correlated with increased in knowledge about HDS use and adverse effects (p = 0.007 and p = 0.001, respectively).
conclusionsApproximately half of the general public in Thailand use HDS, with a small number of reporting adverse events, primarily mild gastrointestinal effects. The public has a moderate level of knowledge about the use and adverse effects of HDS, but there is a need for improved safety knowledge relating to HDS.
