Regular arrangement of collecting venules under endoscopy for predicting a Helicobacter pylori-negative stomach: A systematic review and meta-analysis by Lunan Li; Jiyong Jing; Huiqin Gao; Chenjing Zhang; Haifang Lou; Wensheng Pan is a Medicine article available to read on EtoBox.
## Background and aims: The regular arrangement of collecting venules (rac) refers to the appearance of multiple regular tiny veins in the body of the stomach and is considered to be very effective for identifying gastric mucosa with non-helicobacter pylori infection. this meta-analysis was conducted to systematically evaluate the value of the sign in predicting a helicobacter pylori-negative stomach and the relevant factors that may affect the performance of this prediction. ## Methods: Two biomedical databases (pubmed and embase) were systematically searched through april 20, 2020. the pooled sensitivity, specificity, positive likelihood ratio (plr), negative likelihood ratio (nlr), diagnostic odds ratio (dor) and area under the sroc curve (auc) were calculated. ## Results: Fourteen articles with 4070 patients were included. the pooled sensitivity, specificity, plr, nlr, dor and auc for the rac in predicting non-hp infection were 0.80 (0.67-0.89), 0.97 (0.93-0.98), 24.8 (12.2-50.8), 0.21 (0.12-0.36), 120 (47-301) and 0.97 (0.19-1.00), respectively. ## Conclusions: The rac is a valuable endoscopic feature for the prediction of patients without hp infection.
