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: In Hong Kong, breast cancer is the commonest female cancer. In addition to intrinsic risk factors that cannot be modified, other factors may be potentially modifiable. The objective of this report was to determine modifiable risk factors in association with breast cancer among Chinese women in our locality. Methods: This is a case-control study that enrolled breast cancer patients from the Hong Kong Breast Cancer Registry and healthy matched controls from the local community between 2014 and 2017. Potential risk factors were analyzed using multiple logistic regression. Results: In total, 5186 breast cancer patients and 5571 controls were recruited. Several modifiable risk factors were identified. Self-perceived high stress level (adjusted odd ratios [AOR]= 3.44; 95% confidence intervals [CI] = 3.13-3.78), dairy-rich diet (AOR = 3.33; 95% CI = 2.01-5.52), delayed child-bearing (AOR = 2.23; 95% CI = 1.79-2.79), meat-rich diet (AOR = 1.77; 95% CI = 1.54-2.04), ever use of oral contraceptives (AOR = 1.34; 95% CI = 1.22-1.47), nulliparity (AOR = 1.21; 95% CI = 1.08-1.35), and being overweight/obese (AOR = 1.21; 95% CI = 1.10-1.32) were found to be associated with an increased risk of breast cancer. On the other hand, breastfeeding (AOR = 0.76; 95% CI = 0.69-0.83) and exercise (odds ratio = 0.62; 95% CI = 0.56-0.68) were associated with decreased risk. Conclusions: In our locality, high-stress level, meat- and dairy-rich diet, reproductive history, use of oral contraceptives, and being overweight/obese were identified to be modifiable risk factors for breast cancer. Lifestyle modification may help reduce breast cancer incidence in the coming decades.
