1 · What the graph read from it

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.

2 · The registry

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

backgroundVenous thromboembolism remains a common but preventable complication for cancerous lung surgical patients. Current guidelines recommend thromboprophylaxis for lung patients at high risk of thrombosis, while a consensus about specific administration time is not reached. This study was designed to investigate the safety profile of preoperative administration of low-molecular-weight-heparin (LMWH) for lung cancer patients.

methodsFrom July 2017 to June 2018, patients prepared to undergo lung cancer surgery were randomly divided into the preoperative LMWH-administration group (PRL) for 4000 IU per day and the postoperative LMWH-administration group (POL) with same dosage, all the patients received thromboprophylaxis until discharge. Baseline characteristics including demographics and preoperative coagulation parameters were analyzed, while the endpoints included postoperative coagulation parameters, postoperative drainage data, hematologic data, intraoperative bleeding volume and reoperation rate.

resultsA total of 246 patients were collected in this RCT, 34 patients were excluded according to exclusion criterion, 101 patients were assigned to PRL group and 111 patients belonged to POL group for analysis finally. The baseline characteristic and preoperative coagulation parameters were all comparable except the PRL group cost more operation time (p = 0.008) and preoperative administration duration was significantly longer (p < 0.001). The endpoints including postoperative day 1 coagulation parameters, mean and total drainage volume, drainage duration, intraoperative bleeding volume and reoperation rate were all similar between the two groups. Moreover, coagulation parameters for postoperative day 3 between the two groups demonstrated no difference.

conclusionPreoperative administration of low-molecular-weight-heparin demonstrated safety and feasibility for lung cancer patients intended to receive minimally invasive surgery.
