Smoking affects quality of life in patients with oral squamous cell carcinomas.
Article in Clinical oral investigations, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Smoking is a causative factor in oral squamous cell carcinomas (SCC). Unfortunately, only poor data exist regarding the quality of life of smokers vs non-smokers with SCC. The purpose of this study is to show a correlation between variables for comprehensive interdisciplinary rehabilitation and better patient quality of life (LQ). A total collective of 1,761 patients from 38 hospitals within the German-language area of Germany, Austria and Switzerland (DÖSAK-REHAB-STUDIE) yielding 1,652 patients' questionnaires containing 147 items were evaluated. They refer to the periods before (t1) and immediately after surgery (t2), as well as at least 6 months later (t3). LQ was determined by the patient and ranges from 0% to 100%. Significant differences were found between smokers (80%) and non-smokers (20%) with respect to diagnosis, therapy and rehabilitation. Disabilities and impairments in speech, appearance, chewing/swallowing, pain and LQ were examined. Smokers were more often and more severely affected. Differences were found in the size of the tumour, scar tissue, ingestion, functionality of the facial muscles and a numb feeling in the head and shoulder area. Smoking has a severe effect on the oral cavity. Non-smokers suffer far less from the effects of SCC and the ensuing therapy. During therapy and rehabilitation, the LQ is much higher in non-smokers. This supports the importance of enhanced efforts to inform people about the consequences of smoking so as to prevent them from smoking. Moreover, psychological support might be helpful to give up smoking.
