Article in International journal of high risk behaviors & addiction, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe increasing use of mobile phones in recent years has caused concerns about the effects of electromagnetic waves of mobile phonesonhuman biological processes.
objectivesThis study was conducted in order to survey the effects of mobile electromagnetic waves on electro cardiogram parameters as heart rate, TP segment, PR interval, Time of QRS and T waves, and voltage of R wave. PATIENTS AND
methodsIn this quasi experimental study, 40 students, of Zahedan medical science University, 20 boys and 20 girls, who had referred to the laboratory of physiology were selected. At first a normal electro cardiogram in lead I was recorded for each of the subjects for 20 seconds. Then a mobile phone was placed near their body and while mobile was ringing and talking two other electrocardiograms were recording for 20 seconds. Electro cardiograms were recorded with power lab device and analyzed by chart 5 software. Finally an ANOVA was employed to analyze the data through the SPSS 17, followed by a Tukey test.
resultsThere was significant difference between heart rate during talking in comparison with heart rate during ringing and resting in both genders. There was a significant decrease of resting TP segment in comparison with TP segment during ringing and talking in males whereas in females TP segment indicated significant difference in all three conditions. There was a significant increase in T wave time in males during talking in comparison with resting and ringing; however there was no significant difference in that of females in any of the three stated conditions. This study revealed that there is not any significant difference in PR interval, Time of QRS wave and R wave voltage.
conclusionsAccording to the results of this study, mobile phones can affect the heart rate, TP segment and time of T wave. Therefore, it seems that long term use can affect heart. Based on several reports on the effects of these waves on biological processes, precautionary measures should be taken about using mobile phones.
