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

Exposure to tobacco smoke may be associated with higher risk of nasopharyngeal colonization and infection by Streptococcus pneumoniae (SP), Haemophilus influenzae (HI), and Moraxella catarrhalis (MC). This study was done to determine the influence of passive smoking on S. pneumoniae, H. influenzae, and M. catarrhalis colonization rates among children. This is a prospective cross-sectional study. Tertiary referral centers with accredited otorhinolaryngology-head and neck surgery and Microbiology Departments. In this cross-sectional study, 2-6 years old children in 10 randomly selected day-care centers in northeast of Iran (Mashad) were studied. Smoking exposure and medical history were recorded. Carriage rates for aforementioned bacteria were analyzed on the basis of smoking exposure. 1,125 children (Female/Male: 597/528) with the mean age of 5.05 ± 0.98 years were studied. Carriage rates of S. pneumoniae, H. influenzae and M. catarrhalis among children were 10.1, 8.8 and 6.7%, respectively. Mixed colonization was found in 2.7%. There was a significant difference in carriage rates between children who live in smoking families compare to those with nonsmoking families for M. catarrhalis (P = 0.001) but not for S. pneumoniae, and H. influenza (P = 0.798 and P = 0.117, respectively). It seems exposure to tobacco smoke is associated with increased carriage rate of M. catarrhalis in day-care children.
