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
Purpose: This study investigates the association between secondhand smoke (SHS) exposure and chronic diseases and metabolic abnormalities. Method: This study utilized data from the 2021 STEPwise approach to chronic disease risk factor surveillance (STEPS) survey in Iran. The final analytical sample consisted of 14,448 participants, who were non-smoking adults aged ≥ 25 years and completed all three phases of the STEPS survey. Self-reported exposure to tobacco smoke at home or work was used to categorize participants, while demographic, lifestyle, and clinical data were collected through standardized questionnaires, physical measurements, and laboratory tests. Associations with Cardiovascular diseases (CVDs), Chronic kidney disease (CKD), stroke, heart attack, metabolic syndrome, diabetes, hypertension, hypercholesterolemia, cancer, and multiple chronic conditions were examined using multivariable and multinomial logistic regression analyses, adjusting for age and sex. Result: The study, involving 14,448 participants (mean age 48.59 years, SD = 0.18, 63.37% female), found that SHS exposure is significantly linked to various health risks. Exposure in either home or workplace settings raised the odds for high blood pressure (13%), metabolic syndrome (12%), hypercholesterolemia (18%), diabetes (16%), and hypertension (17%), at least one chronic disease (17%), and multiple chronic diseases (43%) compared to those who were not exposed. Combined exposure (exposed in both home and workplace environments simultaneously) heightened the odds for metabolic syndrome (36%), abdominal obesity (28%), diabetes (22%), increase in high blood pressure (26%), hypertension (33%), a single chronic disease (26%), and multiple chronic conditions (51%). Conclusion: This study underscores the significant health exposure of SHS, linking it to chronic conditions such as CVDs, hypertension, metabolic syndrome, and diabetes. It stresses the urgent need for enhanced public health efforts, such as tougher smoke-free laws and educational campaigns, to lower SHS exposure.
