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
backgroundOutcomes with and without bevacizumab as first-line chemotherapy in Japanese-only ovarian cancer patients have not been reported. In this study, we report a retrospective study conducted at the Tohoku Gynecologic Cancer Unit. PATIENTS AND
methodsThe study included 453 patients with stage III/IV ovarian, fallopian tube, and primary peritoneal cancer who received first-line platinum-based chemotherapy. The patients were divided into two groups: bevacizumab (168 patients) and without bevacizumab (285 patients). The primary endpoint was the rate of platinum-resistant recurrence and the secondary endpoints were the antitumor response, progression-free survival, overall survival, and adverse events.
resultsThe objective response rates for patients with measurable diseases treated with and without bevacizumab were 84.5% and 73.0%, respectively (P = 0.0066). Platinum-resistant recurrence in the groups treated with and without bevacizumab was noted in 31 (18.4%) and 111 (38.6%) patients, respectively (P < 0.0001). The median progression-free survival for the bevacizumab and without bevacizumab groups was 23 and 15 months, respectively (P = 0.0002), and the median overall survival was not reached and 49 months, respectively (P = 0.0005). Hypertension of grade 3 or higher was observed in 21 patients (12.5%) in the bevacizumab group (P < 0.001), and proteinuria was observed in 18 patients (10.7%) and 1 patient (0.3%) in the bevacizumab and without bevacizumab groups, respectively (P < 0.001). Intestinal perforation was observed in only one patient (0.6%) in the bevacizumab group.
conclusionCombination and maintenance with bevacizumab in primary chemotherapy for advanced ovarian, fallopian tube, and primary peritoneal cancer was effective in reducing platinum-resistant recurrence rates and prolonging progression-free and overall survival.
