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

introductionThe correlation between the prevalence and severity of leptospirosis with blood groups has not been investigated so far, but several studies have been conducted to link the infectious diseases with blood groups. The aim of this study was to investigate the prevalence of blood type in patients with leptospirosis and its association with disease severity.

methodsThis is a case-control study performed on hospitalized patients with the diagnosis of leptospirosis in Mazandaran province, Iran, in 2018. The control group was selected from among the families of patients. Blood groups (ABO and Rh) and severity of the disease were assessed. Data were analyzed by SPSS 22.

resultsA total of 300 people (150 in the case and 150 in the control) enrolled in the study. The mean age was 44.35 ± 15.39 years and 81.3% were men. The highest frequency of blood type in both groups was O+, A+, and B+, respectively. There was a statistically significant difference in the frequency of blood groups (

conclusionsAccording to our study, O+ was the most common among patients with leptospirosis. The frequency of O in patients was significantly higher than in the control group, but there was no significant relationship between leptospirosis and Rh. The prevalence of this blood type was higher in people with a severe form of the disease. Finally, there is no statistically significant difference between the severity of the disease and ABO and Rh.
