Efficacy of prothrombin complex concentrate (PCC) versus fresh frozen plasma (FFP) in reducing perioperative blood loss in cardiac surgery: study protocol for a non-inferiority, randomised controlled trial.
Article in BMJ open, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04244981 (Efficacy of Prothrombin Complex Concentrate Reducing Perioperative Blood Loss in Cardiac Surgery, Compared With Fresh Frozen Plasma), which is not on this map.

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.

Abstract
objectiveTo explore whether prothrombin complex concentrate (PCC) is not inferior to fresh frozen plasma (FFP) with regard to reducing perioperative blood loss in patients undergoing cardiac surgery under cardiopulmonary bypass (CPB).
settingFu Wai Hospital, and Peking Union Medical College Hospital in China.
participantsPatients undergoing elective coronary artery bypass grafting, valve replacement or valvuloplasty under CPB, between 18 and 80 years old, will be included.
designThis study is a non-inferiority, randomised controlled clinical trial. A total of 594 subjects will be randomly assigned to two groups (group PCC and group FFP) and given corresponding interventions when at least one of the following criteria is met: (1) international normalised ratio >1.7 measured 20 min after CPB, (2) prolonged prothrombin time or activated partial thromboplastin time (>1.5 times baseline) measured 20 min after CPB and (3) excessive bleeding observed. 4-factor PCC (15 IU/kg) and FFP (10 mL/kg) will be given to group PCC and group FFP, respectively. Preoperative management, anaesthetic and surgical techniques will be standardised for both groups. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome is the volume of blood loss during and within 24 hours after surgery. The secondary outcomes include (1) the total units of allogeneic red blood cells transfused during and within 7 days after surgery, (2) re-exploration due to postoperative bleeding within 7 days after surgery, (3) adverse events and serious adverse events within 30 days after surgery and (4) length of intensive care unit stay and hospital stay. TRIAL REGISTRATION NUMBER: Registered under NCT04244981 at ClinicalTrials.gov on 28 January 2020, https://clinicaltrials.gov/ct2/show/NCT04244981?cond=NCT04244981&draw=2&rank=1. ETHICS AND DISSEMINATION: This study has been approved by the Institutional Review Board of Peking Union Medical College Hospital (ZS-2242).
