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

contextInfluenza results in large numbers of secondary complications and hospitalizations.

objectiveTo assess the impact of oseltamivir on influenza-related complications and hospitalizations by analyzing health insurance claims data for 6 influenza seasons.

designA retrospective cohort study utilizing claims data from the 2000-2005 influenza seasons.

settingClaims data were obtained from Thomson Healthcare MarketScan Research Databases. PATIENTS: Patients prescribed oseltamivir within 1 day of influenza diagnosis were compared to those prescribed no antiviral therapy (controls). OUTCOMES: Frequencies of pneumonia, other respiratory illnesses, and otitis media, and rates of hospitalization, were compared for the oseltamivir and no antiviral groups. Expenditure was also analyzed. Relative risk (RR) for each outcome was assessed using Cox proportional hazards regression.

resultsOverall, 31,674 patients received oseltamivir and were propensity matched to patients with no antiviral prescription. Oseltamivir reduced the risk of diagnosis of pneumonia by 15% (RR 0.85, 95% confidence interval [CI] 0.73, 0.98), other respiratory illnesses by 20% (RR 0.80, 95% CI: 0.76, 0.83), and otitis media and its complications by 31% (RR 0.69, 95% CI: 0.61, 0.79). The greatest reductions in pneumonia risk, of 57% and 52%, were observed for children aged 6-12 years (RR 0.43, 95% CI: 0.26, 0.71) and 1-2 years (RR 0.48, 95% CI: 0.24, 0.99), respectively. Overall, hospitalization rates were reduced by 38% (RR 0.62, 95% CI: 0.52, 0.74) in the oseltamivir group compared with the no antiviral group. Total adjusted expenditures in the oseltamivir and no antiviral groups were not significantly different.

conclusionsOseltamivir reduced the relative risk of influenza-related complications and hospitalization when prescribed immediately upon presentation of influenza.
