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
purposeThis study aimed to investigate a range of patient- and procedure-related factors influencing the success rate and postoperative pain of orthodontic microimplants, and propose potential personalised management strategies based on a large, single-centre dataset. METHODS AND MATERIALS: A total of 853 participants (1,277 microimplants) were included in this single-centre, retrospective investigation. Clinical and demographic information were collected. The primary outcome was implant-level failure within 6 months (yes/no), with success defined as stable retention and function for ≥6 months without severe inflammation or reinsertion. Postoperative pain was assessed at 6 h, 24 h, and 7 days using the visual analogue scale (VAS). Analgesic usage and soft-tissue inflammation were recorded as secondary outcomes. Microimplant success was defined by stable retention over at least 6 months, absence of severe inflammation, and no requirement for reinsertion. Multivariable logistic regression and Cox proportional hazards models were used to identify independent predictors of microimplant failure over time. In addition, a random forest model was employed to rank risk-factor importance.
resultsOverall, 1,089 microimplants (90.8%) remained stable throughout the follow-up period, with a higher failure rate observed among older adults, smokers, and patients with lower cortical bone thickness (P 0.05). High insertion torque (>15 Ncm) significantly increased the odds of postoperative discomfort (OR = 1.85, 95% CI 1.30-2.65). Operator experience also correlated with lower failure and pain scores (P 0.01). The random forest analysis highlighted bone density, insertion torque, and smoking as the top three predictors.
conclusionsIncorporating individualised strategies can improve clinical outcomes. Controlling insertion torque, accounting for cortical thickness, counselling smokers, and allocating senior operators are actionable steps to improve stability and patient comfort.
