The Contribution of Inflammation to Stroke Recurrence Attenuates at Low LDL-C Levels.

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
aimsResidual inflammation risk refers to inflammation that still increases the risk of cardiovascular disease after the level of low-density lipoprotein cholesterol (LDL-C) reached the target (＜70 mg/dL). However, whether inflammation is still an important issue even if very low LDL-C levels have been achieved remains unclear. This study aimed to investigate the contribution of inflammation to stroke recurrence on different LDL-C levels following ischemic stroke (IS) or transient ischemic attack (TIA).
methodsA total of 10499 IS/TIA patients whose LDL-C and high-sensitivity C-reactive protein (hsCRP) were measured were selected from the Third China National Stroke Registry. The cutoff values were set to 25, 35, 45, 55, 70, and 100 mg/dL for LDL-C, whereas the threshold values of hsCRP and interleukin-6 (IL-6) were 2 mg/L and 1.65 ng/L, respectively. Based on each group of LDL-C, Cox regressions were conducted to investigate the associations between inflammation and recurrent stroke within 1 year.
resultsThe associations between baseline hsCRP levels and stroke recurrence were non-significant in groups with LDL-C ＜55 mg/dL (P＞0.05). After stratification by baseline LDL-C of 55 mg/dL, hsCRP ≥ 2 mg/L (10.9% versus 7.5%, P＜0.0001) and IL-6 ≥ 1.65 ng/L (9.8% versus 7.4%, P=0.0002) were found to be related to a high incidence of recurrent IS among patients with LDL-C ≥ 55 mg/dL; however, no associations were observed among patients with LDL-C ＜55 mg/dL. Compared with low inflammation (both hsCRP ＜2 mg/L and IL-6 ＜1.65 ng/L), high inflammation (both hsCRP ≥ 2 mg/L and IL-6 ≥ 1.65 ng/L) was significantly associated with stroke recurrence when LDL-C ≥ 55 mg/dL (adjusted HR 1.38, 95% CI 1.10-1.74), whereas this association was not observed when LDL-C ＜55 mg/dL (adjusted HR, 0.72; 95% CI, 0.41-1.25).
conclusionFor IS/TIA patients, the contribution of inflammation to stroke recurrence seems to be attenuated at a low level of LDL-C.
