The assessment of Ki-67 for prognosis of gastroenteropancreatic neuroendocrine neoplasm patients: a systematic review and meta-analysis.

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
Background: Neuroendocrine neoplasm (NEN) is a group of rare tumors. Among which, gastroenteropancreatic neuroendocrine neoplasm (GEP-NEN) is the most common group. The World Health Organization (WHO) classified these tumors into three different grades (G1, G2, and G3) based on Ki-67 and mitotic rate, and updated the classification in 2019. Several previous studies proved that Ki-67 was related to tumor prognosis, but others still reported that Ki-67 had no predictive value for tumor prognosis. There are different conclusions between studies regarding the correlation between Ki-67 and tumor prognosis, and there is a lack of studies about this correlation of GEP-NENs. Further analysis is still needed to evaluate the prognostic value of Ki-67 in GEP-NENs, to provide reference for clinical decisions. Methods: A total of 303 studies were retrieved that included Ki-67, GEP-NENs, prognosis, survival, and other subject terms and keywords. We excluded studies that did not show complete Ki-67 index, number of patients and 5-year survival data available for meta-analysis, non-cohort studies, articles published before 2000 or not published in English. Fifteen studies were finally included to assess the value of Ki-67 in the prognosis of patients with GEP-NENs using a random-effects model. Results: The cumulative 5-year survival rate for GEP-NEN G1 (Ki-67 ≤2%), G2 (Ki-67 2-20%) and G3 (Ki-67 >20%) was 86%, 65%, 25% respectively. The 5-year survival rate of GEP-NEN G1 (Ki-67 <3%, first revised in WHO classification 2017, redefined WHO classification 2019) and G1 (Ki-67 ≤2%, WHO classification 2010) was 97% and 84% respectively. Conclusions: The overall prognosis of GEP-NENs patients showed a decreasing trend with the increase of Ki-67, which confirmed the significance of Ki-67 index as a prognostic marker for the prognosis of GEP-NENs. Increasing the cut-off value of Ki-67 index for G1 grade from ≤2% to <3% according to WHO classification 2019 did not significantly decrease the 5-year survival rate.
