Supine Positioning in Primary Total Hip Replacement is Associated with a Shorter Hospital Stay Than Lateral Positioning: A Retrospective Propensity-Score Matched Cohort Study.

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
Background: There is still no definite answer regarding the most advantageous patient positioning during total hip replacement (THR). We compared whether patient position (lateral vs supine) incur a difference on hospital length of stay (LOS) after primary THR. Methods: This retrospective cohort study included primary THR patients at a single tertiary center (2017-2022). THR patients prepared in the lateral decubitus position were compared to those in the supine position. Propensity score matching at a 1:4 ratio was applied to minimize selection bias. Matching covariates included age, sex, body weight, comorbidities (hypertension, diabetes), anesthesia time, and intraoperative tranexamic acid use. After matching, 990 patients were analyzed (792 lateral; 198 supine). Results: In supine group, the median LOS (5 days, IQR: 4-6) was shorter than the lateral group (5 days, IQR: 5-6; Conclusion: THR patients in supine positioning have a substantial reduction in hospital LOS compared to patients in lateral decubitus positioning, with supine position providing a 68% reduction in risk of long hospitalization. The two groups showed no difference in blood transfusion requirements.
