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

backgroundCurrently there is no objective measure to determine disease severity in patients with acute influenza infection. During acute viral infections, C-reactive protein (CRP) has been shown to be elevated.

aimTo study the relationship between the symptoms of acute influenza A infection and correlate them with the level of inflammation as measured by serum CRP levels. SETTINGS AND

designProspective study. MATERIALS AND

methodsWe enrolled a convenience sample of adults presenting to an urban academic emergency department (ED), who had positive Enzyme-linked immunosorbent assay detection of the influenza A antigen. The subjects were excluded if they had immunosuppression, liver disease or were currently taking antiviral medication. A previously validated severity of symptom (SOS) score was calculated by asking the participants to record the severity of seven symptoms associated with influenza infection. The subjects had the serum C-reactive protein (CRP) levels tested during their ED visit. STATISTICAL ANALYSIS: A linear regression model was used with CRP as a predictor of the SOS score. Pearson's product-moment coefficient was used to measure the dependence between the two quantities.

resultsThirty-two subjects were enrolled from January through March 2009, and of those, eight patients were excluded from the analysis, leaving 24 study subjects: 58% were women, of ages 18 to 63 years, with a mean age of 31 years (95% CI 25, 37). The mean SOS score was 14.1 ranging from 6 to 21 (95% CI 12.6, 26.4). The mean CRP score was 24.6 ranging from 0 to 64.7 (95% CI 15.8, 33.4). The correlation coefficient between the SOS score and CRP levels was r = 0.65 (P=0.00056).

conclusionThe severity of symptoms associated with acute influenza A infection correlateswith the serum CRP levels.
