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
aimTo determine the immunogenicity of routine vaccination against diphtheria, tetanus, and Haemophilus influenzae type b (Hib) in Asian infants born in the UK, and whether maternal antibody suppression occurs.
methodsA cohort study with 80% power, within 95% confidence limits, to show that 80% or fewer Asian infants would respond with an anti-PRP antibody concentration >0.15 microg/ml. Infants of South Asian origin born in Berkshire were enrolled at two general practices in Reading: 41 Asian families sequentially asked to participate within 2 weeks of birth; 36 infants were enrolled and 34 completed the study. Main outcome measures were: antibody concentration against diphtheria, tetanus, and Hib expressed as geometric mean titres (GMT) and proportion of infants about a threshold protective antibody concentration.
resultsMedian age for completing primary vaccination course was 5 months. All 34 achieved anti-PRP antibody concentration of >0.15 microg/ml, 33 were >1.0 microg/ml, and the GMT was 15.0 microg/ml. All infants developed protective antibody concentration >0.1 IU/ml for tetanus and diphtheria; the respective GMTs were 1.94 and 5.57 IU/ml. Infants with high (>0.25 IU/ml) antibody concentrations against diphtheria and tetanus at 2 months achieved lower antibody concentrations after their three dose course than those with low concentrations (<0.1 IU/ml) (p = 0.06 and 0.03, respectively).
conclusionsDespite evidence for maternal antibody suppression of the response to tetanus and diphtheria vaccination, excellent antibody responses were achieved by routine vaccination according to the accelerated schedule. High vaccine coverage should be encouraged to provide protection against the possibility of imported infection.
