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

We sought to investigate obstetric outcomes and acceptance rates for blood products or types of autotransfusion by Jehovah's Witnesses (JWs) at a single institution in Japan. We retrospectively reviewed cases of 84 pregnant JW patients and 95 deliveries from April 2001 to August 2017. We examined the acceptance rates of blood transfusions, blood products, and autotransfusion types in patients who experienced postpartum hemorrhage (PPH), and investigated estimated hemorrhage volume at delivery and PPH treatments. Of the 84 JW patients, none accepted blood transfusion; however, 75 patients (89.3%) accepted blood products, 57 (67.9%) accepted autotransfusion using intraoperative cell salvage, and four (4.8%) refused all alternatives to blood transfusion. Furthermore, PPH > 1000 mL occurred in 18 of the 95 (18.9%) deliveries. Of these 18 patients, four (22.2%) required blood products and three (16.7%) required supracervical hysterectomy to control PPH. No maternal deaths occurred. Approximately 95% of the patients observed accepted all or some alternatives to blood transfusion. To treat JW patients in a safer manner, understanding their individual acceptance of alternatives to blood transfusion is important for the strategic use of such alternatives.
