Comparison of different preoperative fasting times for pediatric elective surgical procedures: A randomized controlled trial.
Article in Pakistan journal of medical sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05922072 (Comparison of Different Preoperative Fasting Times in Pediatric Patients Undergoing Elective General Anaesthesia), which is not on this map.

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.

Abstract
Objective: To compare the mean residual gastric volume and gastric pH with standard and liberal fasting in children undergoing general anesthesia for elective procedures. Methods: A randomized controlled trial (NCT05922072) was conducted at Department of Pediatric Surgery, Mayo Hospital Lahore from June 2021 to December 2021 and 120 patients undergoing elective daycare surgical procedures under general anesthesia were enrolled. Patients were divided into Group-A (Standard fasting) and Group-B (Liberal fasting). Group-A with 6-, 4- and 2-hours Nil per oral (NPO) for solids/ formula milk, breast milk and clear fluid, while Group-B with six, four and one hour NPO for solids/ formula milk, breast milk and clear fluid respectively. Residual gastric volume and pH were measured after anesthetizing the patient. Effect modifiers like age, gender, duration of anesthesia and procedure were controlled through stratification. Post-stratification, t-test was applied and p-value less than 0.05 was taken as statistically significant. Results: In Group-A, mean age was 6.1±4.5 years and 6.4±4.6 years in Group-B. Mean residual gastric volume with standard fasting was 0.67±0.48 ml and liberal fasting 0.80±0.44 ml (p value 0.13). Mean gastric fluid pH with standard fasting was 1.72±0.78 as compared to liberal fasting 1.63±0.70 (p value 0.53). Conclusion: Free fluid fasting allows for significantly shorter fasting times, though statistically insignificant higher residual gastric volume was recorded in liberal fasting group with a lower pH.
