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

backgroundMultiple sclerosis (MS) pathogenesis involves both environmental and genetic factors. Any stage of life, including the prenatal and perinatal years, may be impacted by environmental factors linked to the onset and progression of MS. It is essential to assess these environmental elements in order to avoid the start of illness. However, there is a lack of research on the effects of parental smoking before childbirth.

objectiveThis study aimed to investigate the association between MS and parental cigarette consumption before childbirth. DESIGN AND

methodsWe conducted a case-control study at Sina Hospital, Tehran, Iran, from June 2023 to June 2024. MS diagnosis was confirmed using 2017 revised McDonald's criteria. Experts created a questionnaire to gather information on parental smoking habits, sex, and age. Patients with incomplete questionnaires or parents with MS were not included in the analysis. The control group comprised patients' companions at the Surgical Ward of Sina Hospital. Binary logistic regression was used to estimate the adjusted odds ratios (AOR) and 95% confidence intervals (CI) for MS onset due to paternal and maternal cigarette smoking, adjusting for potential confounders.

resultsA total of 379 MS patients and 379 controls were included in the study. The mean age of the MS patients was 37.97 ± 9.09 years, while the control group had a mean age of 36.13 ± 12.93 years. Our findings indicated that paternal daily cigarette consumption before pregnancy, adjusted for age and sex, increased the risk of MS onset in offspring by 65% (AOR = 1.65, 95% CI: 1.17-2.31, p < 0.004). Furthermore, paternal daily cigarette consumption during maternal pregnancy increased the risk by 71% (AOR = 1.71, 95% CI: 1.21-2.42, p < 0.002). However, no significant association was found between maternal cigarette smoking, either before or during pregnancy, and the onset of MS in offspring.

conclusionsPaternal cigarette smoking, before and during pregnancy, significantly increased the risk of MS in offspring. These findings highlight the need for further investigation and public awareness, as paternal smoking may represent a preventable risk factor for MS development.
