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

backgroundLeukotriene receptor antagonist (LTRA) therapy reduces asthma exacerbations in children older than 2 years. However, whether early intervention using LTRA in atopic smaller children aged 1 to 2 years who had experienced episodic wheezing can reduce the frequency of wheezing is unknown.

methodsA randomized, double-blind, placebo-controlled, multi-center trial of episode-driven intermittent use of pranlukast for 12 months, one of the LTRAs, was conducted by enrolling children who had two, but not more than two, episodes of wheezing prior to entry and were allergen-specific IgE-positive (≥class 2). The primary outcome was increased episodes of wheezing more than once a month for 3 months.

resultsSeventy-seven children were randomly assigned to receive pranlukast (n = 37) or placebo (n = 40). The primary outcome occurred in 10 of 36 (28%) of the pranlukast group and 14 of 39 (36%) in the placebo group, which was not significantly different (P = 0.45). Even though the study period was extended to a maximum of >5 years, there was no significant difference in the Kaplan-Meier curves in the occurrence of the primary outcome between the two groups.

conclusionsThese results suggest that intermittent and episode-driven use of pranlukast in small children with a prior history of wheezing and atopic sensitization may not reduce the frequency of wheezing later in life. However, the sample size was too small to make a definitive conclusion.
