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
purposeMedication-related osteonecrosis of the jaw (MRONJ) is a serious adverse drug reaction mostly associated to the use of bone-modifying agents. Preventive dental strategies aim to reduce its risk, but the comparative benefit of structured long-term interventions versus a single pre-treatment dental visit remains unclear. This study assessed the impact of a structured long-term, multidomain dental prevention protocol compared with a single baseline dental assessment in patients receiving an oncological-based, high dose (HD) regime of Zoledronic acid (ZA).
methodsBetween 2012 and 2015, two Southern Italian university hospitals enrolled adult cancer and myeloma patients initiating ZA. Participants received either the Standard Protocol (SP), a single pre-treatment dental visit, or the Intensive Protocol (IP), which added scheduled follow-ups and periodontal care. MRONJ was diagnosed using SICMF-SIPMO clinical and radiological criteria.
results202 patients (M/F = 83/119; mean age 63.3 years), were stratified into a SP group (n = 115) and an IP group (n = 87). Eighteen patients developed MRONJ (8.9%). The MRONJ frequency was significantly higher in the SP group (13.9%) compared to the IP group (2.3%) (p = 0.004). MRONJ cases in the SP group showed poorer oral hygiene, a higher rate and severity of periodontitis alongside, and higher post-extraction onset rate.
conclusionMultidomain dental prevention long-term protocol was found to be effective in reducing the incidence of MRONJ by ZA therapy, compared to a single pre-therapy dental intervention, with a potential change of case characteristics. These findings support integrating routine dental evaluation and periodontal maintenance into cancer and myeloma care pathways to improve patient safety and oral outcomes.
