Conditioning intensity and probability of live birth after blood or marrow transplantation, a BMTSS report.
Article in Blood advances, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
We examine the impact of conditioning intensity (low intensity: nonmyeloablative/reduced intensity vs high intensity: myeloablative) and total body irradiation (TBI) on the probability of live birth after blood or marrow transplantation (BMT). Study participants were drawn from the BMT Survivor Study (BMTSS) and included 1607 transplant survivors between 1974 and 2014 at age ≤45 years, with survival ≥2 years post-BMT and age at study ≥18 years. Closest-age, same-sex biologic siblings (n = 172) were 1:1 matched with 172 survivors. Survivors and siblings self-reported information on sociodemographic, chronic health conditions, and pregnancies. Within survivor analysis: the association between the primary exposure variable (no TBI/low-intensity conditioning; 200 to 800 cGy TBI/low-intensity conditioning; no TBI/high-intensity conditioning; >800 cGy TBI/high-intensity conditioning) and the odds of no post-BMT live birth were examined using multivariable logistic regression, adjusting for clinical and demographic variables. Median age at BMT was 31 years (IQR, 0 to 45), and median length of follow-up was 14.3 years (IQR, 2.4 to 41.4); 39.3% were autologous BMT recipients, and 46.6% were female. Overall, 120 (8.7%) survivors reported post-BMT live births. Receipt of >800 cGy TBI/high-intensity conditioning (odds ratio [OR], 3.7; 95% CI, 1.9-7.0; ref: no TBI/low-intensity conditioning) was associated with higher odds of reporting no live birth post-BMT. In contrast, 200 to 800 cGy TBI/low-intensity conditioning (OR, 1.3; 95% CI, 0.5-3.3), and no TBI/high-intensity conditioning (OR, 0.9; 95% CI, 0.5-1.7) were at similar risk of reporting post-BMT live birth as no TBI/low-intensity conditioning. Comparison with biologic siblings: Using conditional logistic regression, we found that BMT survivors were more likely to report no live birth (OR, 2.0; 95% CI, 1.2-3.3) compared with siblings. These findings could inform conditioning intensity options for patients wishing to preserve fertility post-BMT.
