1 · What the graph read from it

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.

2 · The registry

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

purposeTo (1) describe the prevalence of abnormal sleep quality in patients with hip abductor tears (HAT), to (2) determine whether sleep quality improves after open HAT repair, and to (3) to report clinical short-term outcomes in patients undergoing open HAT repair.

methodsThe data of 28 patients (29 hips) who underwant open HAT repair were prospectively analyzed at midterm follow-up. The Pittsburgh Sleep Quality Index (PSQI), modified Harris Hip Score (mHHS), the University of California, Los Angeles activity scale (UCLA), and Visual Analog Scale (VAS) for pain were determined via questionnaire. Paired t-tests were applied to compare preoperative and post-operative Patient-reported Outcome Measures (PROMs). Logistic regression was performed to determine the association between PSQI improvement achievement and demographic variables (laterality, sex, age, body-mass-index (BMI), and preoperative mHHS). The minimal clinically important difference (MCID) was calculated for the mHHS.

resultsA total of 28 patients were included. Four patients (14.3%) suffered post-operative complications after open HAT repair. The predominance of patients was female (77.4%), with a mean age of 60 ± 13 years. The average follow-up was 30.35 ± 16.62 months. Preoperatively, 27 (96.4%) patients experienced poor sleep quality (PSQI > 5); at follow-up, 7 (25%) patients experienced poor sleep quality. Univariate logistical regression analysis demonstrated no significant association between preoperative demographic data and achieving postoperative PSQI < 5. The MCID of mHHS was calculated to be 12.5. Overall, 90% of patients achieved MCID for mHHS.

conclusionPreoperative sleep quality was impaired in 96.4% of HAT patients (PSQI > 5). However, these patients showed an improvement in sleep disturbances after open HAT repair in the early postoperative period. Ninety percent of patients showed significant improvements in mHHS and achieved the corresponding MCID. LEVEL OF EVIDENCE: Case series; Level IV.
