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
objectivePalonosetron is effective for the management of acute and delayed chemotherapy-induced nausea and vomiting (CINV). While emetogenic carboplatin-based chemotherapy is widely used to treat gynecologic cancers, few studies have evaluated the antiemetic effectiveness of palonosetron in this setting.
methodsA multicenter, single-arm, open-label phase II trial was conducted to evaluate the safety and effectiveness of palonosetron in controlling CINV in patients with gynecologic cancer. Chemotherapy-naïve patients received intravenous palonosetron (0.75 mg/body) and dexamethasone before the infusion of carboplatin-based chemotherapy on day 1. Dexamethasone was administered (orally or intravenously) on days 2-3. The incidence and severity of CINV were evaluated using the patient-completed Multinational Association of Supportive Care in Cancer Antiemesis Tool and treatment diaries. The primary endpoint was the proportion of patients experiencing complete control (CC) of vomiting, with "no rescue antiemetic medication" and "no clinically significant nausea" or "only mild nausea" in the delayed phase (24-120 hours post-chemotherapy). Secondary endpoints were the proportion of patients with a complete response (CR: "no vomiting" and "no rescue antiemetic medication") in the acute (0-24 hours), delayed (24-120 hours), and overall (0-120 hours) phases, and CC in the acute and overall phases.
resultsEfficacy was assessable in 77 of 80 patients recruited. In the acute and delayed phases, the CR rates the primary endpoint, were 71.4% and 59.7% and the CC rates, the secondary endpoint, were 97.4% and 96.1%, respectively.
conclusionWhile palonosetron effectively controls acute CINV, additional antiemetic management is warranted in the delayed phase after carboplatin-based chemotherapy in gynecologic cancer patients (Trial registry at UMIN Clinical Trials Registry, UMIN000012806).
