[Effectiveness of annual flu vaccination until week four of season 2018/2019].

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
objectiveAnnual flu vaccination is the most effective measure to prevent the disease and its complications. Vaccine effectiveness (EV) varies from season to season, requiring annual re-evaluation. The objective of this work was to estimate the preliminary effectiveness of the influenza vaccine until epidemiological week 4 of the 2018/2019 season, in patients admitted to a third level hospital.
methodsThe Test Negative Design (TDN) was carried out at the Hospital General Universitario de Alicante. Patients admitted with laboratory-confirmed influenza (RT-PCR positive for any influenza virus, in clinical sample of nasopharyngeal aspirate) and those with clinical suspicion of influenza and negative RT-PCR, from week 40 to week 4 of the 2018/2019 influenza season, were considered as controls. The vaccination coverage was calculated in the cases and in the controls, and the EV with its 95% confidence interval using the formula: EV = (1-Odds Ratio) x 100.
resultsWe included 524 patients: 58 cases and 466 controls. The overall EV for prevention of influenza cases was 42.5 % (95% CI -17.1 to 71.8) and for those over 1 year of age 63.7 % (95% CI 25.4 to 82.3).
conclusionsThe 2018-2019 influenza vaccine is effective in preventing influenza cases in patients admitted up to week 4 of the 2018-19 season. Results are preliminary and may vary and should be re-evaluated at the end of the season.
