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
backgroundJehovah's Witness patients refuse blood transfusion because of their religious beliefs making total hip arthroplasty (THA) challenging. This study aims to determine the safety of THA in Jehovah's Witness patients using standard perioperative protocols as well as evaluate the effectiveness of tranexamic acid (TXA) in controlling blood loss.
methodsDatabases from two tertiary academic centers were queried from 2003 to 2021 to identify THA patients. Demographics, pre- and postoperative hemoglobin (hgb) and hematocrit (hct) lab values, use of TXA intraoperatively, 90-day postoperative hospital utilization, and need for subsequent revision were extracted. Patients who identified as Jehovah's Witness were then compared to a 3:1 propensity score matched cohort of non-Jehovah's Witness patients. Linear regression analysis assessed the effect of intraoperative TXA on change in hgb from pre- to post-THA and logistic regression was used to assess risk of reaching hgb levels < 8.0 g/dL.
resultsA total of 207 non-Jehovah's Witness patients and 69 Jehovah's Witness patients who underwent THA were analyzed. Both groups were found to have similar preoperative hgb and hct as well as postoperative hgb, hct, and hgb shift. Of the Jehovah's Witness patients 3 (6.4%) patients reached a hgb < 8.0 g/dL. Additionally, a higher proportion of Jehovah's Witness patients receive intraoperative TXA (55 [79.7%]) compared to non-Jehovah's Witness patients (127 [61.4%]) (p = 0.01; SMD = 0.41). Logistic regression analysis found that Jehovah's Witness did not have greater odds of reaching a hgb < 8.0 g/dL (OR = 1.03 [0.95, 1.10]; p = 0.49) and that patient who received intraoperative TXA had decreased odds of reaching a hgb < 8.0 (OR = 0.87 [0.80, 0.95]; p = 0.001). Multivariate linear regression found that intraoperative TXA was also associated with a smaller decrease in hgb from pre- to post-THA (β = 0.69 [0.16, 1.22]; p = 0.01). Overall, Jehovah's Witness patients had excellent revision-free (97% [93%, 100%]) and infection-free (99% [96%, 100%]) survival at 7 years.
conclusionAlthough Jehovah's Witness patients refuse transfusion, THA can be performed safely in these patients with excellent implant survivorship by optimizing preoperative hgb levels and utilizing intraoperative TXA. LEVEL OF EVIDENCE: Level III Evidence.
