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

backgroundSecondhand smoke accounts for a considerable proportion of deaths due to tobacco smoke. Although the existing laws ban indoor smoking in public places in Sri Lanka, the level of compliance is unknown.

methodsFine particulate matter (PM(2.5)) levels in 20 public places in Colombo, Sri Lanka were measured by a PM monitor (Model AM510-SIDEPAK Personal Aerosol Monitor). Different types of businesses (restaurants, bars, cafés, and entertainment venues) were selected by purposive sampling. Only the places where smoking was permitted were considered.

resultsThe average indoor PM(2.5) ranged from 33 to 299 µg/m(3). The average outdoor PM(2.5) ranged from 18 to 83 µg/m(3). The indoor to outdoor PM(2.5) ratio ranged from 1.05 to 14.93. In all venues, indoor PM(2.5) levels were higher than the Sri Lankan ambient PM(2.5) standard of 50 µg/m(3). All indoor locations had higher PM(2.5) levels as compared to their immediate outdoor surroundings.

conclusionThe study highlights the importance of improving ventilation and enforcing laws to stop smoking in public places.
