Article in Clinical and vaccine immunology : CVI, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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.
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
Conserved protein antigens have been investigated as vaccine candidates against respiratory pathogens. We evaluated the natural development of antibodies against Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis proteins during childhood. Serum samples were collected from 50 healthy children from their first months to age 13 years (median sampling interval, 6 months). We also analyzed serum samples from 24 adults. Serum IgG antibodies against eight pneumococcal proteins (Ply, CbpA, PspA 1 and 2, PcpA, PhtD, StkP-C, and PcsB-N), three H. influenzae proteins, and five M. catarrhalis proteins were measured using a multiplexed bead-based immunoassay. Antibody levels were analyzed using multilevel mixed-effects regression and Spearman's correlation. Antibody levels against pneumococcal proteins peaked at 3 to 5 years of age and then reached a plateau. Antibody levels against H. influenzae proteins peaked during the second year and then stabilized. Antibody levels against M. catarrhalis proteins peaked during the first year and then slowly decreased. Peak antibody levels during childhood were higher than those of adults. Correlations among pneumococcal antibody levels were highest among anti-CbpA, anti-PcpA, and anti-PhtD antibodies (r = 0.71 to 0.75; P < 0.001). The children presented 854 symptomatic respiratory infections on 586 occasions. Symptomatic respiratory infections did not improve prediction of antibody levels in the regression model. The maturation of immune responses against the investigated pneumococcal proteins shares similarities, especially among CbpA, PcpA, and PhtD. Antibody production against H. influenzae and M. catarrhalis proteins starts early in life and reaches peak levels earlier than antibody production against the pneumococcal proteins. Basal antibody levels are not related to the occurrence of symptomatic respiratory infections.
