Spectral Intra-Lot and Inter-Lot Variability in Methacholine.
Article in Contact in context, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Methacholine chloride is a parasympathomimetic (cholinergic) bronchoconstrictor agent. It is administered exclusively in solution via inhalation for diagnostic purposes, strictly indicated for diagnosing bronchial airway hyperreactivity in adults and pediatric patients aged five years and older who lack clinically apparent asthma. Spectrometric evaluation of a single manufacturing batch, lot P3055R, revealed distinct anomalies, most notably a broad absorbance peak at 5131 cm
