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

backgroundEvidence regarding a preventive impact of antiviral medication for influenza on hospitalization or mortality among non-severe cases is scarce. The objective of this study was to assess the association between the use of antiviral medications in non-hospitalized patients with influenza and their subsequent hospitalization and mortality.

methodsThis multi-center retrospective cohort study used TriNetX, a global database to assess the clinical impact of antiviral medications (oseltamivir, laninamivir, zanamivir, peramivir, and baloxavir) for influenza among non-hospitalized patients. The outcomes included hospitalization, emergency department visit, intensive care unit (ICU) admission, and mortality between 3 and 30 days following influenza diagnosis with the 2-day window period between diagnosis and antiviral administration. Propensity score matching with a 1:1 ratio was conducted to estimate the risk ratio (RR).

resultsA total of 1,016,581 patients with influenza were identified. After matching, 426,275 patients from each cohort were compared. The antiviral-treated group was associated with lower risks of hospitalization (RR 0.91; 95% confidence interval 0.85-0.95; p < 0.001); emergency department visits (RR 0.80; 95% CI 0.79-0.82; p < 0.001), ICU admission (RR 0.84; 95% CI 0.73-0.97; p = 0.016); and mortality (RR 0.60; 95% CI 0.47-0.77; p < 0.001). The sensitivity analysis revealed that the statistical significance in hospitalization was maintained by replacing the 2-day window period with 0 days (RR 0.82; 95% CI 0.79-0.84; p < 0.001). The sensitivity analysis limited to those aged 2 to 64 years without any high-risk comorbidities in the antiviral-treated group compared to the antiviral-untreated group showed fewer outcome events for hospitalization (RR 0.76; 95% CI 0.68-0.85; p < 0.001); ED visit (RR 0.68; 95% CI 0.65-0.71; p < 0.001); and ICU admission (RR 0.48; 95% CI 0.30-0.78; p = 0.002).

conclusionsAntiviral treatment was negatively associated with hospitalization, ICU admission, and mortality. The results need to be interpreted with caution, given limitations.
