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

Surgical removal is the treatment of choice for many neoplasms of the parotid gland. This meta-analysis aimed to evaluate the differences between parotidectomy using a modified facelift incision (MFI) and parotidectomy using a modified Blair incision (MBI). A systematic search of the available literature in PubMed, Embase and the Cochrane Library was performed. Studies of adult patients who underwent open parotidectomy with presumed benign parotid neoplasms based on preoperative examinations were reviewed. The surgical outcomes of the MFI and MBI groups were collected. Intraoperative and postoperative parameters, including operative time, tumor size, cosmetic satisfaction, and incidences of facial palsy, Frey's syndrome and salivary complications, were compared. Dichotomous data and continuous data were analyzed by calculating the risk difference (RD) and the mean difference (MD) with the 95% confidence interval (CI), respectively. Seven studies were included in the final analysis. The pooled analysis demonstrated that the cosmetic satisfaction score was significantly higher in the MFI group (MD = 1.66; 95% CI 0.87-2.46). The operative duration in the MFI group was significantly longer than that in the MBI group (MD = 0.07; 95% CI 0.00-0.14). The MFI group exhibited a smaller tumor size (MD = - 2.27; 95% CI - 4.25 to - 0.30) and a lower incidence of Frey's syndrome (RD = - 0.18; 95% CI - 0.27 to - 0.10). The incidence of postoperative temporary facial palsy (RD = - 0.05; 95% CI - 0.12 to 0.03), permanent facial palsy (RD = - 0.01; 95% CI - 0.06 to 0.03) and salivary complications (RD = - 0.00; 95% CI - 0.05 to 0.05) was comparable between the two groups. Based on these results, MFI may be a feasible technique for improving the cosmetic results of patients who need parotidectomy when oncological safety can be ensured.
