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 Aim: Patients recovering from lumbar spine surgery frequently report persistent pain, functional limitation, and limited understanding of postoperative self-care. This study examined whether participation in a standardized perioperative care program was associated with differences in pain, functional disability, and patient knowledge at 2 months, compared with routine hospital care, among adults undergoing elective lumbar spine surgery in Erbil, Iraq. Method: This was a non-randomized (quasi-experimental) controlled study with two parallel groups and pre-post assessment, conducted between September 29, 2024 and April 25, 2025 in the Neurosurgery Unit of Hawler Teaching Hospital. Participants were recruited by purposive sampling and allocated non-randomly by admission cohort; groups were matched on surgery type and key sociodemographic characteristics. Reporting follows the TREND statement for non-randomized evaluations and the TIDieR checklist for intervention description. Outcomes were pain (Universal Pain Assessment Tool, 0-10), functional disability (Oswestry Disability Index, reported throughout on the 0%-100% scale), and knowledge (36-item researcher-developed questionnaire, scaled 0-100). The primary analysis was the between-group difference in change from baseline, estimated by analysis of covariance adjusted for the baseline outcome value and pre-specified covariates and confirmed by a linear mixed model. Responder, hierarchical-regression, and mediation analyses were pre-specified as exploratory and non-causal. Results: Seventy patients (35 per group) completed the study with no loss to follow-up. Groups were comparable at baseline (all Conclusions: Participation in an intensive, structured perioperative care program was associated with substantially better self-reported pain, disability, and knowledge at 2 months in this selected single-center cohort. Because allocation was not randomized and the program involved considerably greater professional contact than routine care, these findings describe an association rather than a causal effect, and require confirmation in randomized, multicentre trials with longer follow-up.
