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
purposeHead and neck cancers (HNC) significantly impact patients' quality of life (QOL), with oral health often being significantly compromised, especially in advanced stages. Green tea, with its known anti-inflammatory and antioxidant properties, may help to improve oral health in these patients. Therefore, this study aims to investigate the effect of green tea-based mouth rinse on oral health status, pain, and QOL of advanced HNC patients.
methodsThis randomized controlled trial was conducted in the palliative care outpatient department of a tertiary hospital in New Delhi. Then, 64 patients with stage III/IV HNC receiving palliative care were randomly assigned to the experimental and control groups. In addition to usual care, the experimental group used a green tea-based mouth rinse thrice daily for 6 weeks. The study examined oral health status as the primary outcome, which was assessed at baseline and every 2 weeks up to 6 weeks using the Oral Assessment Guide (OAG) and Oral Hygiene Index-Simplified (OHI-S). The secondary outcomes pain and quality of life of the patients were assessed using the Numerical Pain Rating Scale and Oral Health Impact Profile-14 (OHIP-14), respectively.
resultsRepeated measure ANOVA revealed that experimental group had significantly improved OAG-score (F = 34.32, P = < 0.001, ŋ
conclusionGreen tea-based mouth rinse was found to be effective in improving the oral health status of advanced HNC patients. Nurses should incorporate such cost-effective options to improve the oral health of cancer patients.
