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
Background: Temporalis muscle (TM) atrophy is a commonly encountered cosmesis issue following craniotomies. This retrospective study aims to investigate the correlation of clinical and surgical factors with postoperative TM volume and head symmetry in patients undergoing frontotemporal craniotomy. Methods: Medical records were retrospectively reviewed for patients undergoing pterional or middle fossa craniotomy. Pre- and post-operative clinical factors, intraoperative factors, and magnetic resonance imaging magnetic resonance imaging scans were obtained. TM volumes (cm Results: A total of 46 patients were included for analysis, including pterional ( Conclusion: Pterional and middle fossa craniotomy procedures are both associated with significant TM volume loss and subsequent head asymmetry. Age and preoperative scalp thickness are independent risk factors for the development of TM volume loss and head asymmetry. These findings could contribute to the development of preoperative risk stratification algorithms, enabling neurosurgeons to predict the likelihood of cosmetic disfigurement. This would enhance preoperative counseling for patients undergoing craniotomy procedures, especially for elderly individuals and those with thin scalps. Overall, this study provides valuable insights into prognostic factors that may impact the development of poor cosmesis following frontotemporal craniotomy.
