Relationship between neutrophil-lymphocyte ratio and postoperative pain in cesarean section patients done under subarachnoid block: A prospective observational study.
Article in Journal of anaesthesiology, clinical pharmacology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07353138 (The Relationship Between Preoperative Neutrophil-to-Lymphocyte Ratio and Hemogram Parameters and Early Postoperative Pain Scores in Patients Undergoing Septorhinoplasty), which is not on this 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.

Abstract
Background and Aims: Cesarean section is one of the most commonly performed surgeries in obstetrics. Various methods have been employed to assess postoperative pain. Surgical trauma causes acute phase response with neutrophilia and relative lymphopenia. Hence neutrophil lymphocyte ratio (NLR) can be taken as an objective tool to measure acute pain. The primary objective of the study was to evaluate the relationship between postoperative NLR and pain, which was assessed using visual analogue scale (VAS). Material and Methods: A prospective observational study was conducted on 120 pregnant women aged between 18 to 38 years belonging to American Society of Anesthesiologists Physical Status II undergoing elective cesarean section under subarachnoid block, in a tertiary care hospital over 18 months. Postoperatively pain was assessed using VAS. Blood samples were sent and NLR was calculated preoperatively and postoperatively. Injection diclofenac and tramadol was administered for postoperative pain and total doses of respective drugs were noted. The correlation between NLR and VAS was assessed using Spearman's rank correlation analysis. Results: The postoperative NLR was higher than the preoperative NLR. There was significant correlation between VAS score and NLR score at 12 Conclusion: The postoperative NLR correlated significantly with VAS. NLR can be used as a surrogate marker for pain assessment.
