Gender differences in the association between discharge hemoglobin and 12-month mortality after acute myocardial infarction.
Article in Clinical cardiology, 2017. 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
backgroundAnemia at discharge in patients with acute myocardial infarction is associated with poor prognosis; whether this differs in women and men or if there is a threshold value at which these relationships change is unknown. HYPOTHESIS: Women have a lower discharge hemoglobin (Hb) at which outcomes worsen.
methodsWe identified patients with acute myocardial infarction in the TRIUMPH registry between 2005 and 2008. In multivariable models, we evaluated the relationship between discharge Hb and 12-month mortality and tested whether this relationship varied by gender. We assessed whether the relationship with discharge Hb values was nonlinear using a restricted cubic spline term.
resultsOf 4243 patients with AMI, 32.9% were female. Mean admission Hb was 12.9 ± 1.9 g/dL in women and 14.5 ± 2.0 g/dL in men, with mean discharge Hb 11.4 ± 1.8 g/dL and 12.9 ± 1.9 g/dL, respectively. Lower discharge Hb was independently associated with increased mortality (P < 0.05). In multivariable models, discharge Hb decline was similarly associated with increased 12-month mortality in women and men (per 1-g/dL decrease Hb; women HR: 1.24, 95% CI: 1.09-1.42, P < 0.01; and men HR: 1.25, 95% CI: 1.13-1.37, P < 0.01; P for gender interaction = 0.99). The relationship between discharge Hb and 12-month mortality was linear (P for nonlinear spline term = 0.12).
conclusionsLower discharge Hb levels were similarly associated with increased 12-month mortality in women and men. These relationships are linear without a clear threshold, suggesting any decline in discharge Hb is associated with poor outcomes.
