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

backgroundThis study aimed to analyze the effects of anterior descending mandible (ADM) and free superior mesenteric artery (SMAS) folding flaps on post-parotidectomy facial depression.

methodsThis retrospective study examined the effects of sex, age, surgical sample size, method, duration, and blood loss on postoperative complications in 65 patients.

resultsNo significant differences involving sex, age, or sample size for surgical resection were observed between the two groups. The incidence of Frey syndrome (P = 0.175) and the locations of facial nerve injuries and tumors were not significantly different between the two groups. However, a statistically significant difference was observed in postoperative facial depression between the groups (P = 0.045, P < 0.05). No significant difference was found between facial nerve injury and Frey's sign in subgroup analysis of facial depression deformities. Within the facial depression group, tumor locations were significantly different (P = 0.021, P < 0.05). In the cases of facial depression after partial parotid resection, no significant difference was observed between ADM implantation and SMAS flap placement. A significant difference was noted between the ADM implantation and SMAS flap groups in the total parotidectomy group (P = 0.046 and P < 0.05, respectively).

conclusionWomen are more likely to experience facial depression after parotid surgery. Facial depression is most likely to occur after parotid resection if the tumor is located in the deep lobes of the parotid gland. The use of SMAS flaps can prevent facial depression, and both ADM and SMAS flaps can prevent Frey's syndrome. Partial parotid resection reduces the risk of facial nerve injury and facial depression.
