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
abstractGuidelines from the National Heart, Lung, and Blood Institute recommend assigning an Emergency Severity Index (ESI) acuity level 2 to patients with sickle cell disease (SCD) presenting to the emergency department (ED) with vaso-occlusive crisis (VOC) and administering analgesia within 30 minutes of triage or 60 minutes of registration. The American Society of Hematology guidelines recommend analgesia within 60 minutes of ED arrival. In this study of adult patients with SCD presenting to the ED with uncomplicated VOC between 1 April and 30 September 2023, we compared time from triage to administration of first analgesia (TTFA), and time to second analgesia administration (TTSA) for those who were assigned ESI 2 vs 3. Sixty-six visits were included in the analysis. Median pain score at triage was 9 out of 10 (range, 6-10). ESI 2 was assigned to 23 visits (34.8%), and ESI 3 to 43 (65.2%). Four patients who were assigned ESI 3, left the ED without receiving analgesia. For the remaining 62 patients, median TTFA was 65 minutes for those assigned ESI 2, and 178 minutes for those assigned ESI 3 (P < .001), whereas median TTSA did not differ (72 vs 78 minutes; P = .485). In a Cox regression analysis including age, gender, SCD genotype, pain score at presentation, and ESI acuity level, only ESI correlated with TTFA (hazard ratio, 5.731; P < .001). System-based interventions to ensure assignment of ESI 2 can improve adherence to evidence-based guidelines regarding prompt analgesia for patients with SCD presenting to an ED for VOC.
