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

backgroundLittle is known about the significance of haemoglobin genotype in dengue fever severity. This study was undertaken to determine the case fatality ratio and the impact of genotype in patients with sickle cell disease and confirmed dengue fever.

methodsThis retrospective analysis included 40 patients with confirmed dengue and sickle cell disease, during the study period (2010-2012).

findingsThere was a significantly higher case fatality ratio, 12.5% among patients with either haemoglobin SC disease or homozygous SS disease when compared to that of the general population 0.41% (p < 0.0001). The unadjusted odds of dying among those with haemoglobin SC disease compared with the group with homozygous SS disease was OR = 4.4 (95% CI 0.6 to 31.7). The predictors of mortality independent of sickle cell disease genotype were haemoglobin concentration at presentation OR = 0.57 (95% CI, 0.35 to 0.94) and the change in haemoglobin concentration from steady state OR = 0.59 (95% CI, 0.37 to 0.94). Adjusting for haemoglobin concentration at presentation increased the risk of death for the SC genotype relative to SS genotype OR = 13.4 (95% CI 1.1 to 160.3).

interpretationThe risk of fatal dengue may be higher among patients with a relatively mild genotype (haemoglobin SC).
