Strategies for Improving Influenza Vaccination Rates in Patients with Chronic Renal Disease.
Trial report in Deutsches Arzteblatt international, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 1 of them a synthesis that pooled it.
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 influenza vaccination rate among older and chronically ill patients in Germany has declined in the past decade in spite of vaccination campaigns.
methodsThe influenza vaccination rate among persons with chronic renal disease was studied with the aid of billing data from various Associations of Statutory Health Insurance Physicians (Kassenärztliche Vereinigungen, ASHIPs) in Germany. It was tested in a randomized controlled trial whether a written vaccination appeal, sent by physicians to patients, led to an increase in the vaccination rate. It was tested in a further such trial whether the vaccination rate among patients with renal disease could be improved by an appeal for vaccination that was sent by the ASHIPs to the treating nephrologists. Finally, it was also tested in a prospective interventional study whether the vaccination rate could be improved by an appeal for vaccination sent by a health- insurance carrier directly to the patients.
resultsIn 2012-2017, the vaccination rate among persons with chronically impaired renal function ranged from 41.1% to 46.9%; it ranged from 31.7% to 33.7% in kidney transplant recipients and from 42.7% to 44.7% in dialysis patients. An appeal for vaccination that was sent from physicians to patients raised the vaccination rate by 8.3% in the intervention group compared to the control group (p = 0.03; number needed to treat [NNT]: 13). On the other hand, an appeal for vaccination that was sent to the nephrologists lowered the vaccination rate by 0.8% in the intervention group compared to the control group. Finally, an appeal for vaccination that was sent by the health-insurance fund to the patients raised the vaccination rate by 3.2% (p<0.001; NNT: 32).
conclusionFewer than half of all patients with chronic renal failure in Germany are vaccinated against influenza. The vaccination rate was found to be increased only after an appeal for vaccination that was sent directly to the patients. A letter sent to the treating physicians had no positive effect at all.
