Risk factors associated with mortality in patients infected with influenza A/H1N1 in Mexico.
Article in BMC research notes, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 1 of them a synthesis that pooled 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.
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
backgroundInfluenza virus pandemics vary dramatically in their severity and mortality. Thus, it is very important to identify populations with high risks of developing severe illness to reduce mortality in future pandemics. The purpose was to determine the mortality-associated risk factors in hospitalized Mexican patients infected with influenza A/H1N1.
resultsThe risk factors associated with mortality were: male sex [odds ratio (OR) = 5.25, confidence interval (CI) = 1.22-28.95], medical attention delayed >3 days (OR = 9.9, CI = 1.51-64.52), anti-flu therapy delayed >3 days (OR = 10.0, CI = 1.07-93.43), admission to intensive care unit (ICU) (OR = 9.9, CI = 1.51-64.52) and creatinine levels >1.0 mg/dL when admitted to hospital (OR = 11.2, CI = 1.05-120.32). After adjusting for the effects of potentially confounding variables in a logistic regression model, delayed medical attention (OR = 13.91, CI = 1.09-41.42, p = 0.044) and ICU hospitalization (OR = 11.02, CI = 1.59-76.25, p = 0.015) were the only predictors of mortality.
conclusionEarly medical attention is essential for reducing the mortality risk in patients with influenza A/H1N1, while a requirement for ICU management increases the risk.
