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

An outer membrane protein of nontypeable Haemophilus influenzae (NTHi), P6, is a vaccine candidate because it has been characterized as conserved among all H. influenzae strains. Among 151 isolates from children, age 6 to 30 months, evaluating NTHi nasopharyngeal (NP) and oropharyngeal (OP) colonization and tympanocentesis confirmed acute otitis media we identified 14 strains (9.3%) that had variant protein sequences of P6. One atypical omp P6 isolate had sequence mutations in the binding site of a proposed major antigenic epitope of omp P6 identified by monoclonal antibody 7F3. Eight strains (5.3%) had non-homologous variations in amino acids that could result in significant changes to the protein structure of P6, and 5 other strains had amino acid substitutions at four previously described key residue sites. These results show that NTHi omp P6 is not invariant in its structure among respiratory isolates from children.
