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

objectiveAlthough tight glucose control is used widely in hospitalized patients, there is concern that medication-induced hypoglycemia may worsen patient outcomes. We sought to determine if the mortality risk associated with hypoglycemia in hospitalized noncritically ill patients is linked to glucose-lowering medications (drug-associated hypoglycemia) or merely an association mediated by comorbidities (spontaneous hypoglycemia).

methodsA retrospective cohort of patients admitted to the general wards of an academic center during 2007 was studied. The in-hospital mortality risk of a hypoglycemic group (at least 1 blood glucose ≤ 70 mg/dL) was compared with that of a normoglycemic group using survival analysis. Stratification by subgroups of patients with spontaneous and drug-associated hypoglycemia was performed.

resultsAmong 31,970 patients, 3349 (10.5%) had at least 1 episode of hypoglycemia. Patients with hypoglycemia were older, had more comorbidities, and received more antidiabetic agents. Hypoglycemia was associated with increased in-hospital mortality (hazard ratio [HR], 1.67; 95% confidence interval [CI], 1.33-2.09; P<.001). However, this greater risk was limited to patients with spontaneous hypoglycemia (HR, 2.62; 95% CI, 1.97-3.47; P<.001) and not to patients with drug-associated hypoglycemia (HR, 1.06; 95% CI, 0.74-1.52; P=.749). After adjustment for patient comorbidities, the association between spontaneous hypoglycemia and mortality was eliminated (HR, 1.11; 95% CI, 0.76-1.64; P=.582).

conclusionDrug-associated hypoglycemia was not associated with increased mortality risk in patients admitted to the general wards. The association between spontaneous hypoglycemia and mortality was eliminated after adjustment for comorbidities, suggesting that hypoglycemia may be a marker of disease burden rather than a direct cause of death.
