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
backgroudGynecological day surgery patients have dual high-risk factors of both female sex and motion sickness, and the risk of postoperative nausea and vomiting (PONV) is significantly increased. This study aims to observe the effects of penehyclidine hydrochloride or droperidol combined with dexamethasone on preventing postoperative nausea and vomiting after remimazolam-alfentanil general anesthesia for gynecological day surgery.
methods124 patients undergoing elective gynecological day surgery were randomly divided into two groups: penehyclidine hydrochloride combined with dexamethasone group (PD group, n=62) and droperidol combined with dexamethasone group (DD group, n=62). Before anesthesia induction, PD group received intravenous injection of penehyclidine hydrochloride 0.5mg and dexamethasone 5mg, and DD group received intravenous injection of droperidol 1mg and dexamethasone 5mg. Primary outcomes: the incidence of PONV within 24h after surgery. Secondary outcomes: the incidence of PONV in PACU, the severity of PONV within 24h after surgery, sleep onset latency, recovery time, and adverse reactions.
resultsThe incidence of PONV within 24h postoperatively was significantly lower in the PD group (21.3%) than in the DD group (42.6%) (p=0.012). Furthermore, the severity of PONV in the PD group was significantly lower than that in the DD group (p=0.017). There were no statistically significant differences in the remaining observation outcomes (p >0.05).
conclusionPenehyclidine hydrochloride combined with dexamethasone is more effective than droperidol combined with dexamethasone in reducing the incidence and severity of PONV within 24h after remimazolam-alfentanil general anesthesia for gynecological day surgery.
