The presence of emphysema does not affect the systemic bioactivity of inhaled fluticasone in severe chronic obstructive pulmonary disease.
Trial report in British journal of clinical pharmacology, 2004. 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
aimsTo assess the systemic bioactivity of fluticasone proprionate (FP) 2000 micro g daily on sensitive adrenal and bone markers in severe chronic obstructive pulmonary disease (COPD) patients with or without significant emphysema.
methodsTen patients without emphysema (COPD group: age 55 years, FEV(1) 51% predicted and DL(CO) 83% predicted) and 10 patients with emphysema (COPDE group: age 59 years, FEV(1) 43% predicted and DL(CO) 49% predicted) received FP 2000 micro g daily via a spacer for 2 weeks. There was a 1-week washout period prior to FP treatment where patients were given salmeterol and oxitropium, after stopping their usual inhaled corticosteroids for the duration of the study. Measurements including overnight 10 h urinary cortisol excretion corrected for creatinine (OUCC) and serum osteocalcin concentrations were performed at baseline following washout and after 2 weeks of FP.
resultsValues for OUCC and serum osteocalcin concentrations pre- and post-FP were not significantly different between the COPD and COPDE groups. There was significant suppression of OUCC (nmol mmol(-1)) by FP treatment within the COPD group (P = 0.03): 7.86 vs 4.64 (95% CI on the difference 0.47, 5.98), and within the COPDE group (P = 0.006): 7.13 vs 4.27 (95% CI on the difference: 1.03, 4.69). Likewise, there was significant suppression of osteocalcin concentration (nmol l(-1)) by FP treatment within the COPD group (P = 0.04): 7.24 vs 6.34 (95% CI on the difference: 0.01, 1.78), and within the COPDE group (P = 0.03): 6.92 vs 5.72 (95% CI on the difference: 0.12, 2.29).
conclusionsSevere COPD patients who are receiving high dose FP are susceptible to the development of systemic adverse effects, irrespective of the presence of emphysema.
