Clinical outcome of lymphadenectomy in malignant ovarian germ cell tumors: a systematic review and meta-analysis.
Article in American journal of cancer research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Malignant ovarian germ cell tumors (MOGCTs) are predominately diagnosed in young patients and account for most preadolescent malignant ovarian tumors. Currently, due to the high sensitivity of MOGCTs to chemotherapy and the optimal survival rate after chemotherapy, some researchers have recommended opting for non-surgical treatment. However, the effect of lymphadenectomy (LND) on the survival of patients with MOGCT remains controversial. We conducted a systematic review and meta-analysis to compare the clinical outcomes of LND and non-LND in MOGCT surgeries in order to summarize the clinical experience. PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), International Clinical Trials Registry Platform (ICTRP), and Clinical Trials.gov were searched from inception to December 26, 2021. Data on the rates of survival, relapse, and adverse effects were evaluated using Review Manager software. Fourteen studies with 10,759 participants were included in this review. There were 5863 and 4896 patients in the LND- and LND+ groups, respectively. Pooled results showed that although disease-free survival (DFS) was significantly improved in the LND+ group compared to the LND- group (HR: 0.74; 95% CI: 0.56 to 0.97; 2091 participants), LND did not significantly affect overall survival (OS) (HR: 0.82; 95% CI: 0.51 to 1.31; 5298 participants). The operation time was significantly longer in the LND+ group than in the LND- group (P<0.001). Blood loss (P=0.004) and complication rate (P=0.003) were also significantly higher in the LND+ group than in the LND- group. There was no significant difference in mortality rate (P=0.500). LND was associated with an improvement in DFS. However, there was no significant difference in OS in MOGCTs. We recommend that LND should not be a routine surgery for children or young patients with MOGCTs; although it may be beneficial for older people, advanced stage tumors, specific pathological types, and non-chemotherapy patients.
