Treatment Outcome with High versus low-to-moderate Dosing of Corticosteroids in Early vis-a-vis Late-onset Hypoxic Cases of COVID-19: A Multicentric Retrospective Cohort Study.
Article in IJID regions, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Corticosteroid dosing in COVID-19 cases associated with early-onset and late-onset hypoxia have not been separately explored. Methods: In this retrospective cohort study, we divided hypoxic COVID-19 cases into groups based on timing of initiation of corticosteroids relative to onset of symptoms; Group A (≤6th day), Group B (7th-9th day) and Group C (≥10th day), each group being sub-grouped into high and low-to-moderate dose corticosteroid recipients. Cox regression with propensity scoring was used to compare 28-day mortality between high and low-to-moderate dose recipients separately in Group A, Group B, Group C. Results: Among 505 patients included, propensity score matched Cox regression showed greater risk of all-cause mortality among high dose recipients in Group A [HR= 7.35, 95%CI 3.36-16.11, p-value<0·01, N=114] and Group B [HR=3.17, 95%CI 1.65-6.07, p-value<0·01, N=251]. In Group C, mortality was lowest [12.8% (18/140)] with no significant difference between sub-groups [HR=2.52, 95%CI 0.22-29.15, p-value=0.459, N=140]. Kruskal-Wallis Test between Group A, Group B and Group C for six pre-defined exposure variables showed significant differences for Neutrophil:Lymphocyte Ratio (NLR). Conclusion: When steroids were initiated early (owing to an earlier onset of hypoxic symptoms), a high dose of corticosteroid was associated with greater overall 28-day mortality compared to a low-to-moderate dose. NLR, a marker for individual immune response, varied between treatment groups.
