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
backgroundThe therapeutic strategy for stage IB3, IIA2, and IIB cervical cancer is still controversial. The modalities are chemoradiation, radical hysterectomy surgery, or administration of neoadjuvant chemotherapy followed by radical hysterectomy. Response to chemotherapy is determined by tumor vascularization or angiogenesis, proliferative activity, and genetic instability of cervical cancer. The marker of tumor cell proliferation is the Ki-67 protein. In cervical cancer, the p53 gene is suppressed by human papillomavirus (HPV). The HPV E6 protein promotes the degradation of p53 thereby inhibiting stabilization and activation of p53. This study aimed to prove that high expression of VEGF, Ki-67, and p53 are risk factors for a poor response to neoadjuvant chemotherapy.
methodsThis was a case-control study that was conducted at the Department of Obstetrics and Gynecology in one tertiary hospital in Denpasar from October 2021 to April 2022. There were 56 samples included in this study, which were divided into two equal groups, namely good response and poor response to neoadjuvant chemotherapy. Data were analyzed using the software SPSS-24 including the Kolmogorov-Smirnov normality test, Chi-square, and multiple regression logistics. Data were presented in tables and described narratively.
resultsIt was found that the risk of a poor response to chemotherapy on the expression of VEGF VEGF, Ki-67, and p53 were 11.5, 15.0, and 8.33 times, respectively. We obtained a formula for calculating chemotherapy response, y = -7.3+ 1.6 VEGF + 1.6 Ki-67 + 1.8 p53. High VEGF, Ki-67, and p53 expressions were scored 1, and low expressions were scored 2. The limit value used is 0.05. The result y < 0.05 means the risk of poor response to chemotherapy and the value of y > 0.05 means good response.
conclusionThis formulation can be used as a parameter to assess the risk of poor response to neoadjuvant chemotherapy in stage IB3, IIA2, and IIB cervical cancer which can be applied in clinical practice in the treatment of cervical cancer.
