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
Pituitary adenomas are one among the most common neurosurgical tumors with an incidence of 10-25% among intracranial neoplasms (Ezzat et al., Cancer 101:613-619, 2004). Surgical management for the same has been practiced since long, and has evolved from trans cranial approach to endoscopic trans sphenoidal method (Hammer and Radberg, Acta Radiol 56:401-422, 1961). Preoperative radiological analysis with CT &MRI is inevitable in planning endonasal trans-sphenoid surgery to avoid complications because of the high variability concerned with sphenoid anatomy. The present study intends to analyze the incidence of various anatomical variations of sphenoid sinus in a cohort of south Indian population as detected by CT& MRI and assess its impact on surgical approach. Retrospective analysis of CT&MRI images of patients who underwent Endonasal Trans-sphenoidal resection of pituitary tumors at JSS Hospital Mysuru from a period of 2009 to 2020 is done. Anatomical variations of sphenoid sinus esp. degree of pneumatization, sellar configuration, septation pattern, inter carotid distance were evaluated. Results were significant and in concordance with other similar studies. Most frequently encountered pnuematization was sellar type and least was conchal type Sphenoid sinus pneumatization is directly linked to safe access to sella. Presence of septae within sinus need to be identified preoperatively to avoid damage and confusion intraoperatively. A meticulous preoperative analysis of sphenoid sinus anatomy will help surgeon in smooth conduct of a complication free surgery.
