Human placental mesenchymal stromal cell-derived small extracellular vesicles as a treatment for severe COVID-19: A double-blind randomized controlled clinical trial.
Trial report in Journal of extracellular vesicles, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 37 papers, 2 of them syntheses that pooled 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.
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
The current study aimed to investigate the effects of human placental mesenchymal stromal cell-derived small extracellular vesicles (hPMSC-sEVs) as a treatment for COVID-19. This double-blind, randomized, controlled clinical trial was conducted on two groups of patients with COVID-19-associated acute respiratory distress syndrome. After randomization, the control group received standard treatment and placebo, and the intervention arm received standard treatment plus hPMSC-sEVs. The number of hospital deaths was considered the primary outcome. After meeting the exclusion and inclusion criteria, 21 and 24 patients were allocated to intervention and control arms, respectively.
