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
Immunization with pertussis vaccine during pregnancy is recommended in a number of countries to prevent newborn deaths from whooping cough. In some jurisdictions, vaccine uptake during pregnancy is low. We undertook a survey of the knowledge, attitudes, beliefs, and behaviors of pregnant women who had been approached to participate in a randomized, controlled trial of tetanus-diphtheria-acellular pertussis (Tdap) vaccine during pregnancy. A total of 346 women completed the survey. Knowledge about pertussis and pertussis vaccine was generally low; the mean number of correct answers was 10.65 out of 19 questions. Attitudes toward maternal immunization were generally favorable; 51.7%-94.7% of women had positive responses to 10 attitudinal statements. Substantial uncertainty was shown in responses to a number of the attitudinal statements related to vaccination during pregnancy; 22.3%-45.7% neither agreed nor disagreed with the statements. Importantly, 89% of women reported that they would get immunized with pertussis vaccine during pregnancy if their physician recommended it. We conclude that a national recommendation to be immunized with pertussis vaccine during pregnancy supported by their physicians' recommendation would be well received by Canadian women.
