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

backgroundThe present study investigated the association between exposure to electromagnetic waves from widely used devices and pregnancy and birth outcomes among women in Yazd City.

methodsThis study was conducted on a total of 1,666 participants enrolled in the Yazd Mother and Child Cohort Center between 2015 and 2019. Cell phones, cordless phones, and Wi-Fi instruments were considered electromagnetic wave sources. Pregnancy and birth outcomes examined in this study include miscarriage, preterm labor, abnormal birth weight, and deviations in newborn height and head circumference. SPSS version 24 and R-studio version 4.3.1 software were used for statistical analysis.

resultsThe current study revealed that 41 (2.5%) mothers had miscarriage and 174 (10.4%) mothers experienced preterm labor. Furthermore, 181 (10.9%) infants with abnormal birth weights, 117 (7%) infants with abnormal height, and 124 (7.4%) infants with abnormal head circumference were observed in this study. Individuals with longer cell phones call duration during pregnancy had higher risk of miscarriage (p < 0.001, RR (95% CI), 1.0061(1.003-1.0093)), abnormal birth weight (p = 0.002, RR (95% CI), 1.0012 (1.0004-1.002)) and height (p = 0.003, RR (95% CI), 1.0014 (1.0004-1.0023)) in comparison with those with lower cell phone call duration in this period.

conclusionThe findings of the study revealed that an increase in exposure to cell phones during pregnancy can increase the risk of pregnancy and birth outcomes, namely miscarriage, abnormal weight and height of the infant. Furthermore, cordless phone conversations could increase the risk of abnormal weight in newborns.
