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

objectivesPlacenta accreta spectrum (PAS) can induce severe life-threatening obstetric hemorrhage. Herein, we conducted a Bayesian network meta-analysis of previous studies to evaluate the relative benefits of different prophylactic balloon occlusion (PBO) procedures.

methodsPubMed, Embase, Cochrane Library, and Web of Science were searched from inception to July 2021. Blood loss volume, blood transfusion volume, and hysterectomy rate were regarded as the primary endpoints. The data were pooled using a Bayesian network and traditional pairwise meta-analysis.

resultsFifty-nine articles with a total sample size of 5150 patients were included. Compared with no PBO (non-PBO) intervention, PBO of the abdominal aorta (PBOAA, mean difference(MD) - 1.02, 95% credible interval (CrI) - 1.4 to - 0.67), common iliac artery (PBOCIA, MD - 0.84; 95%CrI - 1.36 to - 0.06) and internal iliac artery (PBOIIA, MD - 0.42; 95%CrI - 0.72 to - 0.13) significantly lowered blood loss volume, with PBOAA being more effective than PBOIIA (MD - 0.60; 95%CrI - 1.05 to - 0.17). PBOAA and PBOIIA also significantly decreased blood loss volume (MD - 2.33; 95%CrI - 3.74 to - 0.94, MD - 1.57; 95%CrI - 2.77 to - 0.47 respectively) and hysterectomy rate (OR 0.31; 95%CrI 0.16 to 0.54, OR 0.53; 95%CrI 0.29 to 0.92 respectively). PBOAA has the highest probability of being more effective in reducing the blood loss volume, blood transfusion volume, and hysterectomy rate.

conclusionsPerforming PBOAA, PBOCIA, or PBOIIA in PAS patients is an effective way to minimize blood loss volume, while PBOAA and PBOIIA also reduce blood transfusion volume and hysterectomy rate. PBOAA is a notably more effective strategy to reduce blood loss volume than PBOIIA. KEY POINTS: • PBOAA, PBOCIA, and PBOIIA procedures can significantly reduce the blood loss volume compared to non-PBO intervention in PAS patients, of which PBOAA was more effective than the PBOIIA procedure. • PBOAA and PBOIIA could significantly reduce the blood transfusion volume and hysterectomy rate in contrast to the non-PBO intervention in patients with PAS. • According to our statistical treatment ranking, PBOAA was statistically superior in reducing blood transfusion volume, blood transfusion volume, and hysterectomy rate than other PBO procedures.
