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

Lead (Pb) has adverse effects on our nervous system and renal systems. Young children are more vulnerable to Pb exposure. However, the role of low-level Pb exposure in the immune system and allergic diseases in children is not well established. The aims of this study are to investigate the associations between Pb exposure and allergic diseases; between Pb and immunoglobulin E (IgE) as an intervening variable; and gender-based differences. We used multistage stratified random sampling to recruit kindergarten children nationwide in Taiwan. Information about allergic diseases and environmental exposures was collected by questionnaire. We compared children with and without allergic diseases for blood Pb levels measured by inductively coupled plasma mass spectrometry. The association between blood Pb and allergic diseases was assessed by logistic regression and those between Pb and IgE by generalized linear models. We also conducted mediation analysis to evaluate how much risk of allergic diseases related to Pb exposure is explained by IgE. A total of 930 children completed specimen collections. There was a positive association between Pb and asthma. Blood Pb were also positively linked with serum IgE (β=0.26 kU/l per ln-unit increase Pb concentration; 95% CI 0.009-0.50 kU/l), after adjusting for potential confounders. Analyses stratified by gender revealed that blood Pb correlated with IgE only in boys (β=0.40 kU/l; 95% CI 0.03-0.76 kU/l). We estimated that 38% of the total effect of Pb exposure on asthma is mediated by IgE levels. In conclusion, Pb exposure is associated with both blood IgE and asthma in boys. Moreover, the effect of Pb exposure on asthma may be mediated by IgE levels.
