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

Tobacco cigarette smoking is assumed to be a key reason of death all over the world. Smoking had both severe as well long-lasting effects on hematological constraints. As per the data available from World Health Organization, every year nearly 5 million individuals die around the world due to the diseases triggered by smoking. Cigarette smoking is linked with an elevated risk of cardiovascular diseases. To examine the association between shisha or cigarette smoking and the severity of polycythemia, present study is a cross-sectional organized at King Saud University Medical City during the period from October 2017 to April 2018. Participants were patients who have hemoglobin level above 160 g/L on multiple reading in KSUMC between May 2015-February 2018. The sample size (227 patients) was computed on single proportion formula, Data were collected through questionnaires and from medical record of the patients. A pilot study was conducted to evaluate the validity of the questionnaire. A statistical analysis was performed using SPSS 21.0 version. A p-value of ≤ 0.05 considered as statistically significant. Out of 227 study subjects, 86 (37.8%) were smokers, (61.6%) were cigarette smokers while (29%), shisha smokers. Total (9.3%) were smoking both cigarette and Shisha. 29% patients had high normal hemoglobin between the ranges of (160-168 g/L), 17.6% patients had pre-polycythemic hemoglobin between the range of (169-171 g/L) and 53% patients were having polycythemic hemoglobin (>172 g/L). The hemoglobin level in non-smokers was 168.74 g/L, hemoglobin level in cigarette smokers was170.7 g/L, hemoglobin level in shisha smokers was 171.4 g/L while hemoglobin level in those who smokes both cigarette and shisha was 175 g/L. Smoking has adverse effects on hemoglobin. Shisha or cigarette Smoking is associated with increase in the hemoglobin levels and the severity of polycythemia. The findings may help in raising the awareness of tobacco smokers.
