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

objectives/hypothesisAcute otitis media (AOM) involves an inflammatory response to microbes in the middle ear that facilitates clearance of otopathogens. Clinically, Streptococcus pneumoniae (Spn) infections of the respiratory tract are characterized by greater inflammatory responses than nontypeable Haemophilus influenzae (NTHi) and Moraxella catarrhalis (Mcat). Interleukin 10 (IL-10) plays an important role in down-regulating the inflammatory response. We compared serum IL-10 levels in children before onset, at onset, and after recovery from AOM caused by Spn, NTHi, and Mcat. We sought to determine if IL-10 could serve as a biomarker to distinguish AOM caused by Spn versus NTHi and Mcat. STUDY

designProspective, longitudinal study in a primary care pediatric practice in Rochester, NY.

methodsParticipants were 54 children, 6 to 30 months of age. Outcomes measured were serum IL-10 levels when healthy, at onset of AOM, and after recovery from AOM.

resultsSerum IL-10 was elevated when children developed AOM (P=0.013) due to infections caused by Spn (P=0.011) but not AOM caused by NTHi or Mcat. Middle ear fluid levels of IL-10 mirrored those seen in serum but were 10-fold higher (P=0.02). Other effector cytokines in serum: IL-4, IFN-γ, and TNF-alpha, did not show the same increases as IL-10 at onset of AOM.

conclusionOur study indicates that AOM caused by Spn elicits a significantly higher IL-10 response compared to NTHi and Mcat and may prove to be a biomarker of AOM infections by Spn.
