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
objectiveCaffeine citrate doses >5 mg/kg/day are frequently used for apnea of prematurity. The primary objective was identification of patients maintained on 5 mg/kg/day (Group 1). Secondary objectives included identification of patients requiring dose increases: 7.5 mg/kg every 24 hours (Group 2), 10 mg/kg every 24 hours (Group 3), and 5 mg/kg every 12 hours (Group 4); comparison of demographics and clinical characteristics; and identification of patients requiring dose adjustments owing to caffeine-associated tachycardia.
methodsRetrospective study of neonates born between 23 to <31 weeks' gestation, receiving caffeine between January 1, 2015, and July 31, 2019. Patients receiving caffeine <1 week, initial maintenance dose >5 mg/kg/day, or with congenital abnormalities were excluded. Descriptive and inferential statistics were performed, with a p < 0.05.
resultsOverall, 281 patients were included, with 99 (35.2%) in Group 1; 56 (19.9%) in Group 2; 47 (16.7%) in Group 3; and 79 (28.1%) in Group 4. Significant differences in gestational age were noted, with Group 3 and 4 patients being more premature than Groups 1 and 2 (p < 0.001). Dose increases occurred at a median postnatal age and postmenstrual age of 13.0 days and 31.4 weeks in Group 2; 17.0 days and 30.3 weeks in Group 3; and 16.0 days and 30.1 weeks in Group 4. Significant differences were noted for development of tachycardia requiring dose adjustment, with Groups 3 and 4 having the highest percentage (p < 0.001).
conclusionsTwo-thirds received caffeine citrate doses >5 mg/kg/day, with 44% receiving 10 mg/kg/day. Further exploration is necessary to determine the optimal PNA or PMA for dose adjustments.
