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
purposeWe present a minimally invasive tissue-sparing posterior superior (TSPS) approach that intends to protect the abductor muscles during total hip arthroplasty, prevents the release of the short rotator muscles, and provides the surgeon with the option to repair the posterior capsule. We hypothesized that the TSPS technique would produce a better clinical outcome, faster recovery, and lower complication rates, and that it would not jeopardize acetabular component position.
methodsA retrospective, observational study was conducted in a consecutive series of patients. A cohort of 130 patients (130 hips) operated with a standard posterolateral approach were compared with a cohort of 132 patients (132 hips) operated with a TSPS approach. Patients were assessed with the Harris hip score (HHS) and Western Ontario and McMaster Universities index (WOMAC), which were carried out preoperatively, one month (HHS only), three months, one year, and at four years post-operatively.
resultsCompared with the standard group, patients in the TSPS group showed a faster return to ambulation as reflected in better post-operative HHS and WOMAC scores up until one year (p < 0.05). No significant differences in HHS (p = 0.564) and WOMAC (p = 0.796) scores were found at the four-year follow-up. No major adverse events were observed in either group.
conclusionThe TSPS approach yielded better early clinical outcomes and appears to be a safe and reliable technique. However, these early differences do not appear to be sustained over time, as comparable mid-term clinical outcomes with similar complications rates were observed.
