Humidity control for chronic asthma.
Synthesis in The Cochrane database of systematic reviews, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 5 of them syntheses that pooled 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.
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
backgroundHumidity control measures in the home environment of patients with asthma have been recommended, however there is no consensus about the usefulness of these measures.
objectivesTo study the effect of dehumidification of the home environment on asthma control. SEARCH STRATEGY: A search of the clinical trials registers of the Cochrane Collaboration and Cochrane Airways Group using search terms for asthma and [humid* OR water vapour OR water vapor* OR water-vapour* OR water-vapor*]. SELECTION CRITERIA: Randomized controlled trials on the use of humidity control measures in the home environment of patients with asthma were evaluated for inclusion. Only one trial could be included. DATA COLLECTION AND ANALYSIS: Data was extracted using a predesigned data extraction form. No data was available for entering into RevMan for analysis. MAIN
resultsThe included trial using mechanical ventilation with or without high efficiency vacuum cleaners did not show any clinical benefit to asthma patients. There was a decline in the house dust mite count and the antigen level. This open trial had a low sample size. REVIEWER'S
conclusionsThere is a need for studying the health benefits of dehumidification by a double blind randomized controlled trial with adequate sample size measuring clinical outcomes in patients of asthma.
