Immunogenicity and safety of a novel seasonal influenza preservative-free vaccine manufactured in Kazakhstan: Results of a randomized, comparative, phase II clinical trial in adults.

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
backgroundThe study was aimed at comparative evaluation of seasonal influenza vaccine RIBSP versus commercial vaccine VAXIGRIP® for immunogenicity and safety in the course of clinical trial phase II on healthy volunteers aged 18-60 years.
methodsThe trial involved 150 subjects in randomized 2:1 groups that received either RIBSP vaccine or comparator vaccine VAXIGRIP®. One dose (0.5 ml) of either vaccine contained 15 μg of hemagglutinin of each influenza virus strain recommended by WHO for the Northern hemisphere in 2016-2017 flu season. The observation period lasted 21 day. The trial was registered at ClinicalTrials.gov identifier NCT 03016143.
resultsAssessment of immunogenic activity of the vaccine under study showed that in 21 day the portion of participants with 4-fold seroconversions was 87.0% to A/H1N1; 63.0% to A/H3N2 and 59.0% to B virus. Antibody titer increase factor in the group of subjects that received RIBSP vaccine was 23.3 for A/H1N1; 4.4 for A/H3N2 and 4.5 for B virus. The volunteers that received RIBSP vaccine demonstrated 95% seroprotection level against A/H1N1; 84% against A/H3N2 and 80% against B virus. RIBSP vaccine met the CHMP criteria of the Committee for Medicinal Products for Human Use (CPMP/BWP/214/96). In the course of evaluating the vaccine safety no serious undesirable effects were recorded. All changes of laboratory data were slight and single in most cases. All recorded local reactions have been light in character and these have been predicted reactions observed at vaccination against influenza.
conclusionComparison of the allantoic inactivated split vaccine obtained in vaccines RIBSP and VAXIGRIP®, showed similar immunogenic activity. Both vaccines were safe for the study participants.
