1 · What the graph read from 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.

2 · The registry

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

backgroundOur objectives were to improve the following outcomes in patients with Lyme borreliosis (LB) through an educational intervention in general practice: (i) increase the number of hospital referrals on suspicion of LB, (ii) increase the number of cerebrospinal fluid (CSF) tests examined for Borrelia burgdorferi antibody index, (iii) decrease the number of serum-B. burgdorferi antibody tests ordered, (iv) shorten delay from symptom onset to hospital in Lyme neuroborreliosis (LNB) patients, (v) increase LB knowledge among general practitioners.

methodsA prospective non-blinded non-randomized intervention trial on the island of Funen, Denmark. The intervention included oral and written education about LB and was carried out in areas with an LNB incidence ≥4.7/100.000 between 22 January 2019 and 7 May 2019. Results were compared between the intervention group (49 general practices) and the remaining general practices in Funen (71 practices) 2 years before and after the intervention.

resultsIn the study period, 196 patients were referred on suspicion of LB, a 28.9% increase in the intervention group post-intervention, 59.5% increase in the control group (P = 0.47). The number of CSF-Borrelia-antibody index tests increased 20.8% in the intervention group, 18.0% in the control group (P = 0.68), while ordered serum-B. burgdorferi antibody tests declined 43.1% in the intervention group, 34.5% in the control group (P = 0.30). 25.1% had the presence of serum-B. burgdorferi antibodies. We found no difference in LNB pre-hospital delay before and after intervention or between groups (P = 0.21). The intervention group performed significantly better on a follow-up questionnaire (P = 0.02).

conclusionWe found an overall improvement in LB awareness and referrals among general practitioners but could not show any effect of the intervention on clinical outcomes of LNB.
