Pre-marketing immunogenicity and safety of a lyophilized purified human diploid cell rabies vaccine produced from microcarrier cultures: a randomized clinical trial.
Trial report in Human vaccines & immunotherapeutics, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The large-scale production of a human diploid cell (HDC) vaccine (HDCV) for rabies is limited by several technical challenges. Kanghua Biological Products Co., Ltd., has successfully used microcarrier technology for the large-scale culture of HDCs in bioreactors to develop a lyophilized and purified HDCV. In this blinded, randomized, parallel-group study conducted between July and October 2014 in Mianzhu, Sichuan Province, China, we monitored the safety and immunogenicity of this vaccine in a healthy population vaccinated according to the Essen post-exposure immunization schedule. A hamster kidney cell vaccine was used as the control. Adverse reactions were monitored 0.5, 6, 24, 48, and 72 h post vaccination to assess safety. Neutralizing antibodies in venous blood were measured on day 7, 14, and 72 to evaluate the immunogenicity of the vaccine while follow-up monitoring continued for 1 month. No serious adverse reactions were observed in any volunteer. The incidence rates of systemic and local adverse reactions were, respectively, 10.6% and 2.9% in the test group and 20.0% and 13.6% in the control group. After the third injection, the positive conversion rates of antibodies in the test and control groups were 100% and 98.82%, respectively. In addition, the average antibody titers on day 7, 14, and 42, were respectively, 1.71, 2.72, and 1.29 times higher than those in the control group. These results indicate that HDCV had a better safety profile and higher immunogenicity than the hamster kidney cell rabies vaccine. Trial registration number: 20130602.
