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
backgroundMost influenza vaccines are grown in embryonated eggs and residual egg proteins can cause allergic reactions in patients with egg allergy. The aim of the present study was to determine the safety of inactivated influenza vaccine in patients with egg allergy in Kurdistan Province, Iran.
methodsThis case-control study was done on 876 patients referred to Kurdistan Asthma and Allergy Clinic, Sanandaj, Iran; 635 patients with egg allergy (cases) and 241 patients without egg allergy (controls) from 2012 to 2016. All of the patients were injected seasonal influenza vaccine. Side effects including anaphylactic shock, local reaction, vomiting, coughing, sneezing, wheezing, low blood pressure, redness and itching in the eyes, abdominal pain, dyspnea, oral/facial angioedema, swollen and itching of throat were checked by an allergist within 30 min after vaccination, and followed up to 24 h. Demographic and vaccination data were entered into the SPSS software and analyzed.
resultsOut of 876 patients, 460 (52.5%) were male. Patients' ages ranged from 6 months to 80 yr (mean 13.38 ± 15.22 SD). Overall, 63 patients with egg allergy had local reactions to vaccine. Difference of local reactions between case and control groups was statistically significant (
conclusionAlthough the risk of anaphylactic reactions to influenza vaccine in patients with egg allergy was rare, the vaccine should be administered by an allergist with precaution. The results of present study can be a confirmation of the existing evidences to prevent acute complications to influenza vaccine.
