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
Objective: To investigate the clinical features of peripherally inserted central catheter (PICC)-related thrombosis (PICCRT) within 2 weeks after PICC placement in cancer patients and its dynamic influence on the blood flow status of veins inserted with catheter, and to provide support for implementing thrombosis prevention and control measures. Methods: Between May 2019 and July 2020, patients who had solid tumors and who had PICC were prospectively enrolled at West China Hospital, Sichuan University. Scheduled color Doppler imaging was performed to examine the status of PICCRT formation at 8 points of time, with the first one conducted one day before the insertion of PICC and the other 7 completed within 2 weeks after the insertion of PICC. Then, based on whether patients had PICCRT, the patients were divided into two groups, a non-PICCRT group and a PICCRT group. The PICCRT group was further divided into two subgroups, an asymptomatic PICCRT group and a symptomatic PICCRT group, according to whether the patients had thrombosis-related symptoms and signs. Comparisons were made to study the incidence of PICCRT and the vascular diameter and the blood flow velocity in the veins inserted with catheters at different points of time in the patients of different groups. Results: Among 173 cancer patients in the cohort, 126 (72.8%) developed PICCRT, all of which occurred within 1 week after PICC insertion. There were 95 cases of asymptomatic PICCRT and 31 cases of symptomatic PICCRT. Before and after PICC insertion, the vascular diameter of both the asymptomatic and symptomatic PICCRT groups was significantly smaller than that of the non-PICCRT group and the blood flow velocity was significantly slower than that of the non-PICCRT group, with the difference continuing to increase with the prolongation of catheter indwelling time. Conclusion: Inserting catheters in veins with bigger vascular diameter and faster blood flow velocity may help reduce the incidence of PICCRT. The first week post catheter insertion is the key intervention period for the prevention of PICCRT.
