Efficacy and safety of inhaler steroids in COPD patients: Systematic review and meta-analysis of randomized placebo-controlled trials.
Review in Caspian journal of internal medicine, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundChronic obstructive pulmonary disease (COPD) is a major health dilemma and cause of morbidity and mortality in either industrialized or developing countries and inhaled corticosteroids are widely used worldwide in these patients. In this systematic review, we aimed to analyze the effectiveness of these gents compared to placebo.
methodsPubmed and Google Scholar literature search has been done to find randomized placebo-controlled trials investigating effectiveness of inhaled steroids in COPD patients. Finally, the data from 18 trials had been retrieved and included into a database, and analyzed using Stata ® v.9.0.
resultsData of 12, 297 COPD subjects were analyzed. Analysis of survival of patients in the two groups showed no significant difference between those taking inhaled corticosteroids or placebo (relative risk (RR): 1.071, 95% confidence interval (CI): 0.938-1.224, P=0.309). Patients taking inhaled steroids were significantly less likely to develop an exacerbation episode (RR: 0.697, 95%CI: 0.596-0.816, p<0.001) or to have less withdrawal rate than placebo (RR: 0.882, 95%CI: 0.811-0.960; P=0.004).
conclusionBecause steroid inhalers represent no survival effects in COPD patients, and due to their life threatening side effects (pneumonia, candidemia, etc.), we propose to replace steroid inhalers to cheaper agents which provide patients with comparable advantages (e.g. few exacerbations) and fewer side effects. Pulmonary rehabilitations as well as anti-inflammatory drugs are recommended to be more attended in COPD patients.
