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

backgroundPostoperative Nausea and Vomiting (PONV) is a multifactorial surgical complication with an unclear underlying cause. Anesthetic methods, patients' characteristics and the type of surgery are considered as factors affecting PONV. This study was designed to compare the effect of inhalational and intravenous anesthesia in abdominal surgery on the incidence and severity of PONV.

methodsA single-blinded prospective randomized clinical trial on 105 patients aged 18-65 years was carried out. Patients were divided in two groups of Total Intravenous Anesthesia (TIVA) and Inhalational anesthesia. The incidence and severity of PONV were examined at 0, 2, 6, 12, and 24hours after the surgery. The use of a rescue antiemetic was also evaluated.

resultsFifty point nine percent of the patients in the inhalation group and 17.3% of the patients in the intravenous group developed PONV (p <0.001). The incidence of vomiting was reported in 11.3% of the Inhalational group and 3.8% of the TIVA group (p=0.15), and 24.5% of patients in the Inhalation group and 9.6% of patients in the intravenous group needed an antiemetic medication (p=0.043).

conclusionThe incidence of postoperative nausea and vomiting and the need for administration of an antiemetic rescue drug, and the severity of nausea in patients were significantly lower in the TIVA group.
