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

introductionSmoking is associated with the occurrence and progression of cardiovascular diseases, inflammatory disorders and malignancies.

objectiveTo study the platelet indices, neutrophil lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR) in smokers and their correlation with smoking pack-years.

methodA total of 110 smokers and 110 non-smokers were included. The smokers were grouped into three groups: mild (<5 pack-years), moderate (5-10 pack-years) and heavy (>10 pack-years). The platelet count, plateletcrit (PCT), mean platelet volume (MPV) and platelet distribution width (PDW) were noted. The NLR and PLR were calculated and the statistical analysis was made using the Student's T-test, Analysis of Variance (ANOVA) and Spearman's correlation coefficient.

resultsThe platelet count, PCT and PDW were significantly higher with mean values: 218.56 ± 121.31 vs 203.23 ± 80.35 (p-value = 0.038), 0.27 ± 0.10 vs 0.26 ± 0.10 (p-value = 0.041) and 12.54 ± 1.45 vs 11.99 ± 1.70 (p-value = 0.001) in smokers and non-smokers, respectively. The PLR differed significantly with mean values: 119.40 ± 84.81 in smokers and 181.99 ± 313.09 in non-smokers, with a p-value of 0.045. A significant positive correlation was found between pack-years of smoking and platelet count and PLR with the Pearson correlation coefficient of 0.250 and 0.198 and p-values, 0.008 and 0.037, respectively. The Platelet Count, PCT, MPV and PDW varied significantly between mild, moderate and heavy smoker groups, with p-values of 0.045, 0.010, 0.015 and 0.017, respectively.

conclusionThe platelet indices and inflammatory markers NLR and PLR are derived from routine blood investigations, which are easily available and inexpensive. The monitoring of platelet indices, along with the PLR, can be used as early predictors of morbidity in smokers.
