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

BACKGROUND AND

objectivesThe Rotacaps(®)/Rotahaler(®) system is a single unit dose inhaler being developed to deliver inhaled salmeterol/fluticasone propionate combination (SFC) as an alternative treatment option to the metered dose inhaler and the multi-dose dry powder inhaler, Diskus(®). The aim of this study was to compare the systemic exposure of SFC 50/100 µg following delivery via the Rotacaps(®)/Rotahaler(®) and the Diskus(®).

methodsThis was an open-label, randomized, cross-over, repeat-dose (3.5 days of twice-daily dosing) study comparing salmeterol and fluticasone propionate systemic exposure following inhaled SFC 50/100 µg delivered via the Rotacaps(®)/Rotahaler(®) and Diskus(®), in healthy subjects. Pharmacokinetic sampling was conducted over 12 h post-dose on the last day of each treatment. Pharmacokinetic samples were analysed using solid phase extraction followed by high performance liquid chromatography/tandem mass spectrometry. Co-primary endpoints were fluticasone propionate area under the concentration-time curve over the dosing interval (AUC0-τ ) and salmeterol maximum plasma concentration (C max) on the last day of treatment.

resultsFollowing SFC 50/100 µg Rotacaps(®)/Rotahaler(®), fluticasone propionate and salmeterol systemic exposures were comparable with Diskus(®) in terms of both AUC0-τ [geometric mean ratio (GMR) with 90 % confidence interval (CI) of Rotahaler(®)/Diskus(®) for fluticasone propionate: 0.98 (0.91, 1.06) and salmeterol: 1.04 (0.99, 1.10)] and C max [GMR (90 % CI) for fluticasone propionate: 1.04 (0.94, 1.15) and salmeterol: 0.97 (0.87, 1.08)], meeting the pre-defined criteria for comparability (upper limit of the 90 % CI for the GMRs (Rotahaler(®)/Diskus(®)) ≤1.25]. SFC delivered from both inhalers was well tolerated.

conclusionsSFC 50/100 µg Rotacaps(®)/Rotahaler(®) showed comparable fluticasone propionate and salmeterol systemic exposure to Diskus(®) for all pharmacokinetic endpoints with GMR and both upper and lower limits of 90 % CIs within conventional acceptance criteria for bioequivalence (0.8, 1.25), sufficient for considering progression of the Rotacaps(®)/Rotahaler(®) product for further clinical development.
