BK polyomavirus reactivation after reduced-intensity double umbilical cord blood cell transplantation.
Trial report in Transplant immunology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Serial serum samples from 27 patients who underwent double umbilical cord blood transplantation (dUCBT) were analyzed for BK polyomavirus (BKPyV) DNA by real-time PCR and BKPyV-specific immune globulin by ELISA. Clinical data were collected on all patients. All pre-transplant sera had detectable anti-BKPyV IgG. Fifteen patients (56%) had detectable serum BKPyV DNA (median 8.9 × 10(4) copies/ml; range 4.1 × 10(3)-7.9 × 10(6) copies/ml) a median of 40 days (range, 27-733 days) after dUCBT, with highest viral loads on Day 100 assessment. The cumulative probability of developing BKPyV viremia by Day 100 was 0.52 (95% CI, 0.33-0.71). Six of 15 patients with BKPyV viremia experienced hemorrhagic cystitis by Day 100. By Day 100, there was a trend towards higher BKPyV viral loads in sera of patients with hemorrhagic cystitis than in those BKPyV viremic patients without hemorrhagic cystitis (p = 0.06). BKPyV viremia was associated with significantly higher anti-BKPyV IgM values at 6 months post-dUCBT (P = 0.003). BKPyV viremia occurs early after dUBCT and is associated with a detectable humoral immune response by 6 months post-dUBCT.
