1 · What the graph read from it

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.

2 · The registry

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

introductionExposure to secondhand smoke is a significant public health concern. Our study assessed the level of implementation of smoke-free laws in restaurants in Karachi, Pakistan.

methodsWe conducted a cross-sectional study in District East, Karachi. We randomly selected 40 restaurants based on their meal cost: 17 low (<400 PKR/meal), 12 medium (400-600 PKR/meal) and 11 high-end (>600 PKR/meal). We assessed tobacco control law implementation using an observational checklist that included questions about the presence of no-smoking signs, presence of smokers, people/children near smokers and remains of tobacco products and developed a compliance score for smoke-free laws: compliant (all criteria met), partially compliant (1-2 criteria met) and non-compliant (none met). We asked questions about knowledge, attitudes and practices regarding smoke-free laws with each restaurant's staff. We reported frequencies and percentages for observations and questionnaire responses by restaurant category.

resultsOf the 40 restaurants, 70% (n=28) were either non-compliant or partially compliant, with 82% of low-end and 67% of medium-end were either non-compliant or partially compliant. None of the high-end restaurants were non-compliant; however, 55% partially complied with the smoke-free laws. More than half (53%, n=21) had no no-smoking signs. Smokers were observed on terraces or near children in 20% (n=8) of restaurants, and ashtrays or cigarette packs/butts were found in 40% (n=16). Fifty per cent of restaurant staff (n=20) believed that there was no tobacco control law in Pakistan, only 10% (n=4) knew the particulars of the law and 18% (n=7) were aware of any penalties for violations. In addition, 60% (n=24) reported no visits from legislative or administrative bodies to enforce compliance.

conclusionOur study reveals disparities in the compliance of smoke-free laws between low-end and high-end restaurants, highlighting the need to enforce these laws across all restaurant categories effectively.
