Tobacco use, secondhand exposure and knowledge of secondhand and third-hand smoke among medical college students in Western Nepal: a cross-sectional study.
Article in BMJ open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesThis study was conducted to assess the prevalence of tobacco use, secondhand smoke (SHS) exposure and knowledge about SHS and third-hand smoke (THS) exposure among students in a medical college in Western Nepal.
designThis is a cross-sectional study.
settingData collection was done from 8 July 2023 to 8 August 2023 in a medical college in Nepal.
participantsThis study was conducted on undergraduate students studying in a medical college in Western Nepal using a census (whole population) sampling technique.
main outcome measuresPrevalence of tobacco use was assessed by asking a question, 'Did you use tobacco products within the last 30 days?'. Secondhand smoke exposure and knowledge about SHS and THS exposure were assessed by using structured questionnaires. The χ
resultsThe response rate was 96.43% (n=595/617). The overall prevalence of tobacco use was found to be 16.30%. A total of 88.83% of students from clinical years knew about SHS which was more than preclinical students (p <0.001). The Bachelor of Medicine and Bachelor of Surgery students have higher knowledge of SHS as compared with others (p =0.003). More than 95% of students favoured banning smoking in public places. Nearly half of the participants (45.45%) experienced SHS exposure in the last 7 days. More than half proportion of the clinical students knew about THS, which was higher than preclinical students and interns (p <0.001).
conclusionsTobacco use prevalence among the participants was found to be lower in comparison to other studies including medical students in several Asian countries. Despite more than three-fourths of students knowing the harmful effects of SHS exposure, almost one-half of them were exposed to SHS. The proportion of students who knew about THS exposure was comparably lower.
