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

objectiveElevation of C reactive protein (CRP) is one of the major acute-phase responses following ischaemic or haemorrhagic stroke. This study aims to investigate the associations between platelet indices, neutrophil-to-lymphocyte ratio (NLR) and erythrocyte sedimentation rate (ESR) compared with CRP in patients with cerebral infarction.

settingThe clinical data of patients with cerebral infarction were analysed retrospectively.

participantsWe analysed, unduplicated, 516 patients with cerebral infarction (mean age 66.2±12.7, male/female=291/225). OUTCOME MEASURES: Mean platelet volume (MPV), MPV to platelet count, NLR and ESR were compared with CRP in patients with cerebral infarction in a single institute through Spearman correlation test.

resultsThere were significant correlations between CRP and MPV (ρ=0.088, p=0.045), NLR (ρ=0.4, p<0.001) and ESR (ρ=0.468, p<0.001) in patients with cerebral infarction. In the male group, NLR (ρ=0.398, p<0.001) and ESR (ρ=0.502, p<0.001) showed significant correlations with CRP. In the female group, CRP showed significant correlations with MPV (ρ=0.17, p=0.011), NLR (ρ=0.392, p<0.001) and ESR (ρ=0.475, p<0.001).

conclusionsMPV, NLR and ESR showed significant correlation with CRP in patients with cerebral infarction. MPV and NLR are cost-effective and simple parameters that can be attainable by using an automatic haematology analyser. Further well-designed and large-scale prospective studies are warranted to evaluate platelet indices or NLR for monitoring patients with cerebral infarction.
