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

backgroundSurgical resection is the main treatment for pheochromocytoma (PHEO). Although open surgery (OS) has been shown to be safe and feasible, the safety and efficacy of laparoscopic surgery (LS) for PHEO remain controversial due to the uncertain effects of pneumoperitoneum on haemodynamics and the complexity of the tumour itself. This study was performed to compare the treatment outcomes of OS with those of LS for patients with PHEO.

methodsA systematic search through November 11, 2019, was conducted. All studies comparing outcomes of LS and OS for PHEO were included according to eligibility criteria. This meta-analysis was conducted using Review Manager Software, version 5.3, and STATA software, version 12.0. The quality of the included studies was assessed using the Newcastle-Ottawa scale.

resultsFourteen studies involving 626 patients were included in this meta-analysis. LS was associated with lower rates of intraoperative haemodynamic instability (IHD) [odds ratio (OR) = 0.61, 95% CI: 0.37 to 1.00, P = 0.05], less intraoperative blood loss [weighted mean difference (WMD) = - 115.27 ml, 95% confidence interval (CI): - 128.54 to - 101.99, P < 0.00001], lower blood transfusion rates [OR = 0.33, 95% CI: 0.21 to 0.52, P < 0.00001], earlier ambulation (WMD = - 1.57 d, 95% CI: - 1.97 to - 1.16, P < 0.00001) and food intake (WMD = - 0.98 d, 95% CI: - 1.36 to - 0.59, P < 0.00001), shorter drainage tube indwelling time (WMD = - 0.51 d, 95% CI: - 0.96 to - 0.07, P = 0.02) and postoperative stay (WMD = - 3.17 d, 95% CI: - 4.76 to - 1.58, P < 0.0001), and lower overall complication rates (OR = 0.56, 95% CI: 0.35 to 0.88, P = 0.01). However, no significant differences in operative time, postoperative blood pressure control, rates of severe complications, postoperative hypotension or cardiovascular disease (CVD) were found between the two groups.

conclusionsLS is safe and effective for PHEO resection. Compared with OS, LS caused less IHD, providing an equal chance to cure hypertension while also yielding a faster and better postoperative recovery.
