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

purposeThe objective of this study is to examine the factors that contribute to the occurrence of hidden blood loss (HBL) in individuals with ankylosing spondylitis (AS) who undergo posterior correction surgery.

methodsFrom October 2019 to September 2023, 186 patients with AS who were scheduled to have a posterior orthopedic correction surgery were included in our study. The patient's demographics, bone mineral density (BMD), operative time, hospital stay, intraoperative blood loss, blood transfusion volume, type of corrective osteotomies, the number of pedicle screws and fusion segments, drainage volume, correction angle of kyphosis and laboratory examinations, including preoperative hematocrit (HCT) and platelets (PLT

resultsWe reviewed 186 consecutive patients in our study. Potential risk factors of HBL included BMI (P = 0.050), BMD (P = 0.013), operative time (P = 0.002), the number of fusion segments (P = 0.001), the number of pedicle screws (P = 0.033), type of osteotomy (P < 0.001), correction angle (P = 0.005), and PLT

conclusionHBL constitutes a significant proportion of perioperative blood loss in individuals with AS who received posterior correction surgery. BMD, type of osteotomy, and PLT LEVEL OF EVIDENCE: Level III.
